We get the blow by blow account from Sirius (In GOF, I think).

[Snape *wanted* to know where Lupin dissappeared to each month so 
Sirius  *told* him just get a stick and poke the knot in the 
Whomping Willow and you'll find out all you need to know.]

Thats the account we have and I don't question it. Sounds like an 
act of spite. And personally, Sirius out of the blue one day decides 
to tell Snape how to get in....? this account of the incedent speaks 
to me of a retaliation.  Blackmail or jinxing, plots of murder?? now 
thats just gossiping Pippin!
