Jen: I assumed Lupin meant it was Snape's specialty as a DE, not at 
school. 

Lupin won't disparage Snape to Harry in HBP, when he cuts him off 
with 'People have said it many times.  It comes down to whether or 
not you trust Dumbledore's judgement.  I do; therefore, I trust 
Severus.' (HBP/Very Frosty Christmas)  All bets are off when Lupin 
believes Snape betrayed Dumbledore's trust though.  Next to the 
aurors, Lupin is depicted as the character who knows most about the 
harsh reality of battle next to the Aurors, he's the one who talks 
about the enemy they'll be facing in DH, and he believes Snape is not 
only an enemy, but a very dangerous enemy because Snape's been privy 
to Order information.  As a former DADA teacher and soldier, it makes 
perfect sense to me that Lupin would've taken time to learn more 
about Snape.  

How would he learn?  Well, Lupin is hanging around Moody for one 
thing, who 'was wearing a look of deep skepticism behind Dumbledore's 
back' in the Pensieve memory in GOF ("The Pensieve") when Dumbledore 
vouched for Snape.  Moody's the source imo, even if the words are 
Lupin's.
