. I think Knee angulation as well as ankle flexion are tools to modulate edge control, and is something many good skiers use subconsciously, and expert skiers consciously use to to great advantage.
I think Cirquerider really hits the nail on the head with this comment/definition.
"Is knee angulation bad?" Of course not. Possibly a better question would be, "how much knee angulation is needed and when is it need in relationship to the location of the turn"? I'd say it depends on the desired outcome.
I believe angulation is generated by the varied rotation of 4 components, hip/knee/ankle/foot and is used to gain/develop edge angles (tipping), vary or tighten the turn radius and facilitate fore/aft edge pressuring (torque). Generating angulation is all about creating, loading and controling edge pressure and angles so the ski will turn.
BTW, really good thread here. I think the reason the comments are so varied is that "generating angulation" is quite variable and the amount and combination of mechanical movements is really dependent on the desired intent/outcome/need of the turn.
As seen in the OP's video, generating knee angulation early in the turn results in higher edge angles in the high C and increased pressure to the shovel edges which tightens the turns radius and shortens the arc length. The shovel edges are hooked up throughout the turn, but the tails are brushing at the bottom of the turn. If the skiers added more ankle rotation/extension and foot twist throughout the turn, the radius would be even tighter and the arc length even shorter, which would result in a "rounder" turn where their bodies stayed more in the fall line and the skis would come across the fall line quicker and at sharper angles.
I'm way out of my league when it comes to racing gates, but it looks to me, when comparing Ted to Bodie, Bodie is slightly late at the gate as his skis are still leaving the fall line, where Ted's are already returning. I believe Bodie is seen generating knee angulation here and probably rolling his ankle to in an effort to develop torque to increase shovel edge pressure tighten the turns radius.

I have heard the argument many times that the foot/ankle can not angulate or twist but it is an easy fact to prove!
I agree and there is no doubt the ankle can angulate. I think the ankle does 3 things, it rotates, angulates and flexes/extends. I refer to it as "rolling" the ankle over, but i admit that description over simplifies the movements and we can see any of them, which makes describing these vital movements so difficult and understanding them so complex.
I could never execute this turn in this location without knee angulation, a lot of it is certainly not "bad thing" in this instance and I could never get my skis to come across the fall line this sharply down the backside of a mogul without ankle angulation either.
