Hickengruendler:

No. He couldn't see everybody, who was in the Shack on the map, because 
the shack wasn't on Hogwarts grounds. He only saw Lupin entering the 
secret passage under the Whoomping Willow and followed him, because he 
thought he met Snape. (At least supposing he was telling the truth. It 
might have nothing but a lie, but the story as he told it is believable 
and does not have the hole you mentioned).
