Hardly a coincidence Alan when the source for the shadows comes from Andrej who has to be consistent 
As I understand it, Barry, Andrej has asked himself how Prayer Man can be so far forward (i.e. on the first step down) without his left forearm catching sunlight. His solution has been to give Prayer Man a turn eastwards so that said forearm remain far enough back to stay in the shade. I think he's misread the image and given himself needless trouble! The way I read the image, PM has his arms folded.
He is deliberately staying out of the sun---------and has chosen the
farthest point forward (=1 step down) that still allows him to do this.
The Darnell image with contrast boosted suggests that only his left elbow----------which Andrej is mistaking for his right hand-----------
may be catching direct sunlight. The 'left forearm' IMO is something
behind PM!
Here's the thing.
The animation shows how his own block fits neatly in front of PM, not in his place, contradicting everything he's been working toward for months.
So do we congratulate him or ban him? Light a candle, say a prayer or take up square dancin'?
Not sure that's what Andrej's done here, Barry. He's simply placed a 5"2' block (=5"2' as measured to his doorway model) at the very edge of the landing and seen what happens if he extends it across the landing.
He's not suggesting the block is in front of PM.
