both had left to live. His curse may have missed the DE's hand
(luckily for Snape) and hit poor George's ear by mistake, but it kept
the DE from completing his Avada Kedavra (or from aiming it properly).

Snape's Sectumsempra curse and swerved out of the way to avoid being
hit by it "accidentally."

"Snape saved Lupin", because there is just not enough canon to support
this idea. The chase scene is described very briefly in the memories,
and there is nothing in it suggesting that the DE swerved etc. Your
(and mine :-)) scenario seems very probable, but still, the DE could
have missed Lupin for some other reason than his desire to avoid
Snape's "accidental" Sectumsempra.

Carol:
Then why have the scene at all, except as a red herring to make Snape
look evil? Lupin lived; I doubt that he would have lived if Snape
hadn't interrupted that Avada Kedavra with the Sectumsempra which we
know he cast. We also know that Snape shouted the spell rather than
casting it nonverbally. If I heard Snape shouting "Sectumsempra," or
even "Sec--!" I'd get out of the way instantly. 

As little canon as there is for our explanation, there's none at all
for a Killing Curse that missed Lupin for "some other reason." And why
else would *Snape*, who is a superior duellist, miss his target,
another DE's hand, unless that hand moved out of the path of the spell?

Snape was trying to save Lupin's life. Lupin lived. Therefore, barring
some other unknown and unmentioned factor, Snape saved Lupin's life.

Carol, who doesn't think you need to be afraid of stating the obvious
interpretation of the scene
