But when another Death Eater hit Harry from behind Snapes warned him off by shouting "No! Have you forgotten our orders? Potter belongs to the Dark Lord! We are to leave him!"

So by my reckoning the mere fact that Snapes didn't kill or kidnap Harry is meaningless.

Jury is still out on who's side Snapes is on.

"No! Have you forgotten our orders? Potter belongs to the Dark Lord! We are to leave him!"

That's another thing I'm not so sure about. Voldemort doesn't really have a reason for Harry NOT to be killed by just anybody. At the end of OOTP, Bellatrix was trying to kill Harry when VM showed up--he was upset about the prophesy being destroyed but he didn't say anything about Bellatrix trying to kill Harry. Could it be that Snape has been leading the Death Eaters to believe that HP must be left for VM? They all seem to realize that Snape has VM's special favor. I think they'd believe anything he says.
