"Just for aguments sake have the man facing the centre with the lady backing the centre but to his right side.The man turns 1/4 turn to the right. where would you say the man is and the lady in relation to each other."
That depends on if they have TURNED (changed direction of progression) or if they have ROTATED (cbm'd with no change of progression yet).
In the TURN case, the man will pass the lady.
in the ROTATION case, the lady remains on the whole ahead of the man, however the man will now be stretching his head and to an extent left side past her.
In the turn case, the man traveled past the lady. In the rotation case, he stretches past her, but has not actually passed her.
In a natural turning figure, step one achieves the stretched past result of CBM rotation, but the actual TURN or MOVING PAST does not occur until step 2. In something like a feather, you only have the CBM/stretch past on step one, because you do not seek to actually pass your partner and change direction on step two. That's basically the difference between a natural and a feather - step one is fairly similar in either case, but step two is entirely different (which has slight implications for a difference in the end of step one)
