Major SPOILERS ahead...Okay, I think I've figured out how Sherlock carried out the impossible leap. He had Molly locate a recently dead corpse who fit his general body type and then had her make a mask of his face and apply it to the corpse.
He also had her haul the corpse up to the roof of the place where he had arranged the confrontation with Moriarty.
And then it was a snap to throw the corpse over the ledge of the roof. What do all the die-hard Sherlock fans think?

It was lovely to see a young Rupert Graves in "A Room With a View" an old Merchant-Ivory film I watched last night.
