Yas is a downhill and telemark instructor. Good eye. (CANSI is our telemark/nordic association here.)
TDK is a good skier. His javelin turns don't appear to create the same outcome at all as in those CSIA demos - his free ski does not point the same direction as his hips. It's been artificially torqued by the foot. See here where the hip points one way (slightly to the outside of the turn) and the free ski points a different way (far outside the turn):
If you do this exercise and use the free ski as a compass for your hips, there should never be any tip crossing above the fall line--unless you're skiing square to your skis (and why would you do that in high end skiing?). Above the fall line, while your hips point more downhill than across the hill, your free ski will point more downhill than the stance ski. Only as you steer the stance ski will the tip pass under your free ski.
So I'm not sure if TDK was trying to create a different outcome by twisting the free ski. Given how much emphasis TDK's placing on carving and linking, rather than turning the lower joints, I don't think he is creating the same outcome at all. So comparing TDK's javelin turn to those CSIA ones is like comparing apples to oranges.
Met, have a look at what Ted Ligety is doing.. Lots of early counter above the fall line... Inclination as well. It's an effective way to pressure the ski from the moment it's tipped on edge.
