From that article...
Salchow and loop jumps must takeoff backward to receive full credit under ISU rules that are now being enforced by technical panels. Some coaches teach their skaters to pivot on the toe pick until they are totally forward just before they lift off the ice. These jumps are downgraded.
Makes absolutely no sense and is dangerous. That article is worthless.
Since I'm feeling fun today, I've gone through and taken screen caps of all Mao Asada's take-offs from her Free Skate (except the second double axel, which has basically the same as her first as far as the take-off is concerned). According to that article you linked, all of her jumps should have been deemed Underrotated - literally all of them... Even the double jumps...
I'll post them in the order she executes them in her program.

I think that's the order she performed them, not that it matters.
Some of them I snapped earlier than I would have preferred, but I wanted to avoid a frame skip. Point being, according to that article you're citing, every single one of her jumps would be deemed UR just due to the take-off, but that's simply not what the judges are doing, because any decent judge knows that it's not possible to consistently train and land jumps safely trying to jump going backwards - ESPECIALLY for edge jumps. If you're a really strong [vertical] jumper you can pull a Yu Na Kim and jump-rotate a Toe Loop or Flip, maybe even a Lutz if you're an athletic phenom - going backwards - but a triple axel off a straight line would lead to a ton of URs since you won't have any decent rotational energy transference, and Triple Loop/Salchow straight off a backward edge will probably eventually land you in the hospital).
The only jumps of Mao's that I would UR due to the take-off are the Axels. She has bad technique on the take-off and rotates WAY too much on the ice before she takes off. It's literally the only reason why she can even dream of doing a triple axel. With a proper (i.e. clean) take-off she wouldn't even be close because she simply doesn't jump high enough. The take-offs for her double is basically the same, however she has more than enough airtime since that one requires less due to less rotation in the element. Her Double Salchow actually rotated past forwards before she left the ice, but I chalked that up to coincidence since she did double it and that is possible the reason why she decided not to do the triple. That one I'd have probably UR'd as well for rotating too far across before taking off.
As for the jumps that look somewhat before forwards, notice the knee bend she still has in the screen caps. She's already that far, and hasn't actually taken off yet. Just covering that base.
After watching the slow motion, the triple toe loop in combination with the double axel is clearly UR on the landing, so the judges actually got that one right.
What that article states probably applies to the 1920s to 40s when most skaters did single jumps in their programs. Yep, I can do a Salchow or Loop single off a clean edge, too. But no one could pay me to do doubles that way, because concussions aren't fun.
And for fun:
Dick Button's Triple Loop in 1952. Note the Take Off Mechanics.
As for the Lutz discussion:
It sounds more difficult than a triple-axel take off, to be honest.
A Lutz take off IS almost as difficult than an Axel Take-off. Axel take-off is like a forward Loop take, off, basically. Two things jump out when you compare the two:
1. Axel is a forward edge take-off with no assistance. Psychologically that is more difficult than any backward take-off. Additionally, the Axel comes with the risk that the skater can let their weight fall back too far and completely destroy the jump. If you slip off the edge you will Waxel. There is no assistance. It is exceedingly hard to Salvage an Axel compared to pretty much any other jump.
2. The Axel has an extra half rotation over the Lutz, which indirectly increases the risk:
- You have to Jump higher.
To jump higher, you either need some insane verticle jump skills, or you need more speed. To quote Kim Yu Na about her Lutz: "The faster I go, the higher I jump."
You have to pull in tighter.
More Speed, More Height, Tighter Rotations = Really Volatile Landings. Harder to Control and very hard to check out of (having a good knee helps this). That's why you don't see many 3Axel-Loop (or Quad-Loop) combinations in Skating. The jump is rotating so fast and tight that it's impossible for most skaters to check out of it properly to put a loop after it. In most cases, they'd end up doing 3 turns out of the first jump.
The only ladies that have done truly clean triple axels in competition so far are Ito and Harding. I think Tiffany Chin may have done a couple, but I personally haven't seen them (I should look into that...). Asada's jump is so cheated on the take off, that with the allowances the rules leave on the landing her "triple Axels" often rotate (in the air) less than the average triple toe loop or salchow. Let's just hope the judges don't decide to crack down on it at the wrong time.
As for Asada suddenly fixing her jump issues. She will have to do the best with what she has. I think it's a bit naïve to expect any factorable changes in her technique between now and then. She's had the same funky take-offs and UR isues since 2005 in some cases. She only seems to have improved because she actually regressed quite a bit over the years and is only recovering form that regression (similar to Slutskaya's 98/99 years, except she came back with improved jumps and Mao just came back with a renewed fixation on a flawed 3Axel jump).
