Are the outcomes equivalent or do they all have different outcomes?
BigE, I'm not quite sure what you are asking here. I'll give it a try though.
1: Maintains effective alignment of the inside half of the body, in particular foot to hip. Not needed if functional inside half tension is maintained throughout the turn. We always need someplace to move from and to. Particularly in the fore aft plane.
2: Key to success in tai chi chaun is the ability to maintain our root and to smoothly flow between and exchange one root for another. Moving from our waist requires that we always maintain our root to help cultivate and ground our energy so that we can get all parts to move in unison to serve our intent. To me skiing is like this, and though I'm no expert on waiststeering, I would say that the intended outcomes from one and two are similar.
3: Have no idea.
4: To me gait mechanics used in skiing simply means a smooth transfer of our root or stance leg from one to the other. This can happen through ILE or through OLR, or anywhere in between. They all require good functional body mechanics and alignment to happen, along with a good reading and understanding of the forces.
5: PSIA lead change? Have no idea what you mean by that.
