Friends, it's possible, of course, that the excellent Stancak has found the solution to Prayer Man's location but that his suggested posture of left knee bent up a step------------

-------------is incorrect.
Prayer Man's upper body could be exactly as Stancak proposes, and his right leg could be on the first step down as Stancak proposes, BUT
---------------his left knee could be bent beneath him, allowing the ball of his left foot to rest on the landing
OR
---------------his left leg could be crossed over his right leg, allowing the ball of his left foot to rest on the first step down.
Try standing on a stairs like this, folks. I have just done so and they're both perfectly natural and easy postures, allowing one to lean in comfortably to the right hip. No health & safety issues raised! 
All we have to do is ask ourselves one easy question; Do the women on the east in Darnell who are turned even further to to side have to have their legs up?
Can you even imagine those woman putting their legs up in a public place?
So I agree Alan, it just doesn't have to be and might be better without it.
The leg up has always been an interpretation and we've been straining to see it, it loses nothing when it's gone, could still be all on the step like those girls opposite PM, one of whom was pregnant, so even less likely to get her leg
over up.
