If Snape is DDM and if Harry needs Snape's help to defeat 
Voldemort AND if Snape was the one to cast the freezing 
charm that saved Harry from Fenrir, then Harry's realizing 
that fact could be the discrepant event that causes him to 
start re-evaluating his opinion of Snape.  Something is 
going to have to happen to make Harry change his mind .

There are two things that make me suspicious of the second 
Petrificus Totalus.  One is the fact that it is so much like 
the first one that the temptation is overwhelming to assume 
that the caster is the same in both cases.  And yet the 
circumstances are just ambiguous enough to make it plausible 
if that turns out not to be the case.

The other thing is Harry's peculiar lack of ability to 
recognize voices, pointed out to us by the fact that he 
hears Petunia's howler from Dumbledore, but doesn't recognize 
that it was DD's voice until DD tells him a year later.

I agree that if it wasn't Snape who froze Fenrir Greyback, 
then it is not significant who did and we are not likely to 
hear any more about it.
