Politically I can conclude that this statement is true. Marketing is about perception, not reality. The plain truth is that its not as simple in practice as many would have you believe and that is the reason for the confusion throughout skiers.
If you keep a 50%-50% pressure distribution between your feet while turning, independent leg steering is very easy to control and accomplish without any problems keeping the hips from rotating. This would include using steering to create a pretty crisp carved turn.
The problem arises when we start to move away from the 50-50 pressure thing. All of a sudden it becomes much more difficult to control or coordinate the two feet parallel. The inside foot wants to steer easier than the outside foot so, the inside foot wants to create a wedge or diverge throughout the turn. Since the body likes symmetry and control, the hips want to naturally rotate to balance the steering feeling between the feet. This might even cause the outside foot to skid.
As we approach a 90-10 ratio or even greater pressure on the outside ski, fore and aft pressure differences on the inside ski become nearly as effective as leg steering and therein lays the differences we see in philosophy. Once you are 100% on one foot you only have pressure difference for control or upper body rotation.
Myself I have explored both avenues and as some here know, I have advocated both methods of turn control. Lately as I have gained more experience with either, I am coming down on the side of leg steering. Why? Cuz the older I get the more I resemble a 55 gallon drum and its easier to support higher overall pressures on two feet instead of one. I can get great angles by a combination of leg steering, inclination and angulation to achieve more of a 50-50 pressure and when I do, the control of leg steering is precise and easy to control. This is especially true in less than ideal conditions. Now that is just my opinion.
