SSSusan:
Yes, I think Potioncat is right.  Whatever Snape knew or suspected, 
really, he could have just been attempting to stop some evil 
*individual* wizard who wanted to attain immortal life.  Since Voldy 
hadn't been seen or heard from for 12 years, Snape could **easily** 
plead "How could I have known??" if he'd been confronted by Voldy 
later.
