zgirnius:
If I might suggest a reason young!Snape would think this - he knew 
nothing about the Marauders being Animagi and running about transformed 
with transformed Lupin on full moon nights. In other words, as far as 
he knew, it was as important to the Marauders that Lupin stay locked 
away and isolated in the Shack as it was to anyone else. 

Yet Sirius knew the secret for entering the passageway, and the most 
logical source of that information was Lupin. (Since, I presume, the 
other possible sources would have been Pomfrey and Dumbledore). Why 
else would Lupin tell Sirius, if not to set up the 'prank'?
