Could be that a particular technical model might have reason to dogmatize against certain movements, no doubt, though I think if there is not a clear and justifiable reason then I say that technical model is flawed or inadequately described.
In this case I think it might be one of those things where if ski instructors are lifting up their inside ski a lot, it can be confusing for students, good or bad, for high end dynamic skiing I don’t have a problem with it, but if a student watches it and then starts doing goofy stuff, then could be a potential issue. I can see why the psia technical model might frown on it for no other reason. The current psia technical model is really not very well defined so these kinds of memes tend to float around with different theories about it. In fact I don’t believe you will find anywhere in the psia technical manual that both skis need to be engaged in the snow at all or most times. No such requirement or justification for that is made anywhere, officially. But there are dozens of common memes such as this one floating around the ranks and amongst various clinicians, examiners, etc..sometimes they are things that people just think don’t look good. This is one of them, right up there with fear of narrow stances and other things like that. Where your hands should be, etc. imho it’s more about a certain undocumented image a lot of people seem to think is the visual to shoot for, with minimal consideration for the actual functional implications. In my view, that is not a technical model at all, it’s a lack of one.
