There's a huge difference between consciously knowing and unconsciously knowing. Most champions were unconscious competents before they had to teach, and hence, had to know. Unfortunately, they impart the knowledge backwards, and their students usually don't come anywhere close to their level of competence.
Knowing the different "positions and contact points" makes a tremendous difference, ask Mirko and Edita, as QPO noticed they certainly think it is important. So does Luca, Johnathan and Ieva Pauksana who are the sources where I originally started to learn body mechanics.
Ah, none of them are Body Schoolers, so that makes sense that their approach is polar-opposite to where my response was coming from.
When you are learning, especailly teaching someone to go into promenade to show and know that the girl is behind the man's right hip connecting at her inside left hip is not useful information? That the lady is behind the man's hip being the "contact" and they form a shallow V creating a "promenade position" is not worth mentioning or knowing? It's okay that they come out hip to hip and both facing square on to LOD, which, due to lack of information happens in most cases?
In locks or any outside partner position you would not want to know or show where the man and woman contact each other or is it okay for them to be hip to hip and being flat because knowing where the connection is, is not useful?
Everything you’re describing is the end result and not the action required to create the end result. I might agree that it’s useful for the teacher to know, but why would the student need to know unless the student is planning to teach very soon? Learning how to do and learning how to teach are two very separate things. The teacher would need to know the end result so that the student can be evaluated and corrections can be made to the student’s actions if necessary.
Same foot lunge or contra checks is it okay for the girl to be overturned away from the guy or the guy to be overturned because knowing where they contact and knowing the position is not worth knowing?
More results, not the actions necessary to create the proper end result. If the student knows the actions necessary to create the end result, the end result will always be correct, the student need not know any details about the end result. A good result is something that happens when the actions are done correctly. All the student needs to know is the execution.
