The normal forward spiral dating back to the beginnings often went into a charlotte-like spiral. Not every skater was that limber, but some were.
It must have been w-a-a-y back to the beginnings. I don't know of any top skater that used it in competitve program before Michelle Kwan. I'm pretty sure that it was not in the repertroire of Barbara Ann Scott, Tenley Albright, Carol Heiss, Peggy Fleming, Katarina Witt, Kristi Yamaguchi, Oksana Baiul, or Tara Lipinski.
All the references that I can find on this move refer to it as an "archaic show maneuver" (like an airplane spin, I suppose), that you saw in professional extravaganza's but not in competition.
One source says, "This is a move that Michelle Kwan found in the archives" [more likely, Frank Carroll did, LOL]. Peggy Fleming raved about it at 1999 Nationals when Michelle first put it into her Arianne LP. Within two years, everyone was trying it, LOL.
BTW, that same year Michelle also put another unique move into her Fate of Carmen short program [more likely Lori Nicole did] -- a couple of high kicks like a Rockette, from a position standing on her toe pick. It was pretty amazing, but she never did it again (and no one else picked it up, either). Every year during that stretch Frank and Lori seemed to come up with yet another unusual embellishment to add to Michelle's repertoire.
In her
Rush SP/exhibition number the next year Michelle deliberately changed the choreography to put the jumps and her layback spin a little earlier, so she would have time to give the Charlotte it's full due as a program highlight.
About edging, all of the definitions of the move that I can find say specifically that the Charlotte is performed on the flat. This one is typical:
"Charlotte Spiral: Also known as a "candlestick spiral”, the Charlotte is a backward spiral performed on the flat of the blade..."

Because it is a move done on the flat, you can go backward in a straight line and hold the position for a long time and cover a great distance, which is what really sells the move, IMHO.
If you are on an edge, it seems to me that you would not be able to keep your center of gravity over your skate for more than a few seconds, plus, you would be curving ("spiraling") toward the center of your circle. As for a
change of edge spiral, I think Zuranthium nailed it with his "flamingo in death thoes."
So I think if Caroline Zhang does come up with a legitimate variation of this position, on an edge and as part of a CoP-approved spiral sequence, I agree with Passion's post above. Caroline deserves that 1-point bonus for an original and unique move.
