Yes, I agree, they did move differenlty...yet I bet you they never thought about moving they just moved. I miss nothing.
No trained athlete, dancer, martial artist "just moves" without having given a lot of thought to how they develop patterns of movement and why - each of us, once we have absorbed certain basics by imitation and rote, if we take our training at all seriously begin to consciously model certain patterns based on internal and external priorities, interests, capabilities, etc that we each foster by our own trial and error, experimenting, exercise, visualisation, etc.
Even on the most basic things like rowing exercise or tai no henko, I never mindlessly "just move" - one day I may be playing with weighting, another day with being big, another day with breathing. Don't most of us?
