My take, when a WC athlete weights, unweights, counter-weights, tips, rotate the legs, couter-acts, manages pressure, blocks a pole plant, or stems (as Bode does when appropriate), there is a clear intention there that is tempered by the reality that the end result is measured by the hundredth, which means that the integrity of the ski in the snow and conservation of momentum between the wand and the eye are the only thing that matters, where form must absolutely follow function, where technique and tactics become one and the same.
Learning to ski is different than learning to race if for no other reason than the vast majority of skiers learned (and habituated) how to use the skis as a brake pedal long before (if ever) realizing it was a gas pedal too. Some of the fundamental movement patterns for creating and maintaining speed, regardless of the lexicon used to describe them (e.g. PSIA, PMTS, or scientology) are 180 degrees out of phase with those of braking. If Harald's intent is to race fast, he fails, but if the intent of his movements is control with nice body lines on varying terrain and surfaces, he does quite well.
Semantics at times frustratingly rule the day when comparing one teaching method to the other; let's not forget that the rest of the world also have their own ideas about teaching and doing this sport, some of them very successfully. Pro tip: if anyone would like to build a career for themselves, simply invent a dictionary of brand new terms to describe how we move, file for copyright protection, and state repeatedly that everyone else is wrong.
At the end of the day I'm reminded of the text of the Shurangama Sutra explaining how teaching only serves as a guidepost to the truth, e.g. PSIA, PMTS, and the like are the fingers that point to the skiing we seek, but only so we can experience the skiing directly ourselves.
