Sherlock’s Fall Explained

So here’s a short roundup of how I think Sherlock cheated death.

May be SPOILERS here.

The first part is that Sherlock got Molly to dress up a corpse like Sherlock. This combined with the cyclist hitting Watson and drugging him with the drug from the previous episode (the Hounds of Baskerville). This would make Watson see Sherlock when Watson checks Sherlock's pulse. 

When Watson checks Sherlock’s pulse his hand is looking pretty old. So probably not Sherlock. 

Watson wouldn't see Sherlock hit the ground because Sherlock asked him to stand behind the little building (as we can see below).

Sherlock did fall, but he fell into the removal truck that was parked by the building. Molly's associates put down the body prior the fall.

The removal van moves away, the paramedics get there (unrealistically quickly) and don't take his body to the ambulance…Just down some dingy alley.(Its come to my notice that this is a hospital, so maybe not that quickly or dingy)

The sniper then sees Watson acting sad and packs away his riffle. 

Here's the video.(There's actually a continuity error at 4.08 where the removal truck should be closer to the body)  

It's probably more ingenious than what I have deduced, but we'll all have to wait until next year to find out.

Any better ideas?
