Potioncat:
It's not a popular explanation, but I think is one of those moments 
JKR referred to in which she had painted herself in a corner. I'm not 
sure if she noticed, though.

In PoA DD tells Harry that the Order has more efficient means of 
communication. And JKR confirmed (I think) that the method was 
Messenger Patronuses. So I think it was pretty clear that JKR was 
thinking that Snape had sent a Messenger Patronus to 12 GP.  Only, 
that doesn't work if it would reveal to everyone that Snape loves/is-
devoted-to Lily.

I've seen several very good explanations of what Snape may have done 
rather than send a Patronus (in fanfic form) but I think JKR 
overlooked this important detail of a problem.
