Doesn't Voldemort know about Snape's loyalty?

Ariston:
Hmmm... well, if Snape *is* acting as a double agent (yes, it's a
big if, but I still think it's an open possibility, see below) -- if
he is acting as a double agent, then both sides realize that he has
to look like he's accommodating to the other side. So it wouldn't
make sense, for example, for him to be the one to actively lure
Harry to the DoM. <snip>

Neri again:
I also tend to the possibility that Snape is a double agent, and in 
general I agree with what you wrote. However, this argument doesn't 
hold anymore if one of the sides believes it's end game. In Voldy's 
case, he thinks (and with a very good reason) he can capture both the 
irking Potter and the Prophecy in a single move. This looks very much 
like the decisive blow that will win the war for him, and for such an 
objective blowing Snape's cover would be worthwhile. So it seems 
Voldy values Snape enough not to kill him, but not enough to trust 
him with the most important missions.
