Ghost you are making the assumption that twisting the skis is steering the skis. Twisting is pivoting and we are not talking about pivoting skis when steering for clean carving.
What I call steering, some call passive rotation of the femurs in the hips sockets to allow us to ski in and out of counter or to affect counter balance. I will add that for me this is not passive as I add a bit of muscle tension to positively guide my skis parallel to one another and in the direction of the turn. Adding a slight bit or steering tension lets me be much more aware of my feet and their parallel relationship to one another. That tension also allows me to tip my skis more progressively throughout the turn. No tension equals no feedback. I would not call this enough twist to leverage the front of the skis in torsion. I ski at a DIN of 5.5 and never twist out.
As JASP has pointed out some people use more tension than others to tighten a turn. My knees won't take the kind of tension that JASP probably can.
