"Lady's NT. Alignment:(1)backing DW,(2)Pointing LOD(3) Facing LOD. Amount of turn:(1) Com turn to R,(2)3/8 btw 1-2 body turns less,(3)Body completes the turn. The man indicates to the lady what variation he wants her to dance and then follows her."
No, he does not indicate a natural turn and follow her through it, he indicates one bit at a time that results in them both having danced a natural turn, ideally with the ending alignments given above. This is important - those are where the steps end up, but not necessarily where they go immediately. If the lady "knows" it's a natural turn and positions her foot in the "correct" place, you get the look of two heavily schooled students who aren't actually dancing together, but both doing the excercises their teacher taught them.
"He does not dance her second step for her. She has to make way for him to pass. He does not dance through her."
He does not move her body, but continuous guidance is proved either by the man (at points of inflection) or by intertia (in between points of inflection) - though really it's always some of both.
"If she dances the Technique correctly she is setting the diretional path."
No. It may look this way because to an outside observer the path is first visible in the lady's foot, but it's actually given by sublte details of the movement of the man's body - you just may not be used to looking for it there, or dancing with those skilled enough to pick it up from this. With a good dancer the opening of the lady's foot and hip is not a one-shot deal, but something that happens progressively as the man's body moves through (yes, THROUGH) the space over her standing foot.
"The man has to follow the lady's path even when it is wrong or he will pull her of balance."
Yes, everyone has to adjust to their partner. One thing many men are not aware of - one key clue to who is dancing a routine and who isn't - is that depending on how the lady responds, you may get into a situation where you should dance a next figure different than what you had intended.
"Hopefully she will be following his leads but many times she does not especialy if his lead is weak or anougther couple may be in the way or there is misunderstanding as to what variation they about to dance."
She's going backwards in the NT, so hardly going to see a collision before he is. There should be no misunderstanding about what variation is being danced, because the lady never dances variations. Variations are abstract concepts for discussing over coffee in the prep room - dancing is about following your partner. If it's not lead, or dictated by the inertia of what was previously lead, then don't do it, that simple.
"If your partner is as heavy and as tall as you are ,you won't be able to bully her."
You partner can be a foot shorter and half your weight, but if she doesn't carefully match the position of her weight in her feet to the position of your weight in your feet, you cannot get her to do what you want without distorting the connection in the ways pro-am teachers commonly resort to.
