I think the vid / stills ref is a deliberate windup.
You got access to the vid dense?
I'll post up some sequence pics from the vid when i get a chance.The way Iain did it involved getting two shit small edges quite far up and left then running feet up until RF is on pocket/pinchy bit of arete then bouleing for top edge with left.
