"Their is also a rule to be observed which is on this particular step, and that is, any step to the side comes from a toe to a toe. That!s why it is down in the book as THT"
No, I understand that perfectly well. The problem is that you failed to understand the issue raised in the post you responded to - you failed to look up the quick open reverse and note the precise similarities and differences between that and the feather finish.
"On the Reverse Turn step 4 for the man it is before the next step 5 is taken. Which gives us a THT"
Yes, but your theory ("Their is also a rule to be observed which is on this particular step, and that is, any step to the side comes from a toe to a toe. That!s why it is down in the book as THT") for why this happens is flawed, because your theory also predicts that this should happen for the lady on quick open reverse, and it does not happen there.
To be accurate, your theory of why the man's action should be THT on the inside of the feather finish needs to not imply that the lady's action on the inside of the quick open reverse should also be. It needs to recognize that in that case the footwork is instead TH, NFR - in other words, the heel rising only AFTER the the next step is placed, not BEFORE as in the case of the feather finish.
