2-turn - you're correct, I was at the end of the turn and I think I was just entering the transition (with skis flattened) when the destabilization occurred. Note though that terrain uneveness and pressure changes would also allow for that inside ski to accidentally slip under the outside ski too.
This is the point in time that I have had many an edge catch, so far I have been fortunate to not hurt myself. It seems that at the moment that there is less pressure on a ski it gets squirrely and is easy to catch an edge (whether it be at the transition of a turn or just gliding at high speeds).
Happened twice to me this past weekend, both times after exiting a high speed nearly 90* turn. After completing the turn and basically relaxing I caught an edge on my weaker leg (left), I was able to correct, but it was a scary feeling, I am assuming my alignment is off....but maybe its just the nature of a shaped ski.
These wide shovels make it easier to catch an edge, especially when the ski is not full engaged on edge. At the transition of an aggressive turn, it is possible that only the tip (widest portion) of the inside ski is making contact. At that point all that is needed for a catastrophe is for the front edge to catch or get derailed due to little or no pressure and it will be deflected to the underside of the outside ski.
I think the problem lies in putting too little pressure on the inside ski, not the other way around. I think that this also falls in line with the fact that the subjects are very experienced skiers and feel the confidence and have the ability to transition into turns with such speed that the inside leg basically gets airborn from unweighing it and from the liveliness (spring) that the shaped skis afford.
