"Anonymous Soale and Gioia picture 104082. Being that Soale's partner Gioia's back foot is in exactly the same position as is Jonathan Wilkins partner Katusha in picture 104186."
If that is true, and if their intention is to step from there into promenade then it is WRONG.
Wrongness does not depend on who you are or what you have won. It depends on the practicality of what you are attempting to do - and such a turned out orientation of the back foot is not beneficial for movement in promenade. It goes against all history of teaching, too!
"The perfect position would be with both feet on an equall angle. But being that the photos where taken in rapid succession there it is more likely that we have an unfinished foot position."
Since you now seem to be agreeing with me that the proper foot position would be self parallel, and this is clearly not that, then either we are seeing mistakes, or the foot position still changes before the movement. Both are possible.
