Interesting discussion on how pressure is created. IMO the key to creating pressure is early edging of the skis.
We established above that at speed you have to have a large edge angle in order to hold the turn, that means that in transition you don't really pressure the skis from the CoM. You have some pressure, but just enough in order to turn them by edging/tipping.
It is very important what you do with the skis in transition. When going into transition the CoM and skis are on diverging paths. In order to get them into converging paths again you need to edge the skis early so that they start to turn into converging paths.
If you tip too little the paths will still be diverging and you are forced into washing the tails out to get the convergence.
If you tip a bit more so that the paths are parallell the skis will not wash out, but parallell paths does not give you any free pressure purchase so you are forced to extend and that will pretty much destroy the rest of the turn.
If you tip a lot so that you have converging paths you have a lot of energy that must be directed, and that translates directly into pressure. If you have the outer leg tall at this point you get the pressure without excerting yourself.
If you do it really good you get the converging already in the high C.
Note that if you pressure the skis muscularly too soon the CoM and skis will not converge as much and you will not get any "free" pressure later.
I hear coaches say "put more pressure on the skis" all the time without explaining how to do that.
I think JASPs description is another way of getting the aforementioned convergence, but even if you feel that you get it through steering I think that a "steering movement" of edge locked skis actually lead to tipping and that this is what turns the skis, not the steering in itself. Assuming of course that we are still talking about carved turns.
