The 97 WC Qualifying Combo in that video is probably the most textbook 3Lo3Lo ever done in competition, followed closely by the Nagano combo.
No jump that is so small can possibly be textbook. The technique was not perfect either. She does start pulling very quickly rather than jumping up and then rotating. That's the only way you can possibly rotate a jump with such little height. But yes it was commendable.
As for the Russian girls doing quads, I highly doubt it. Sotnikova may be able to get the height, but she probably doesn't have enough control on the air position to do a quad.
I'm surprised that more girls haven't already been heavily training the Triple Axel, though. Ever since the post-2010 rule changes, it has been an extremely valuable element for the SP.
