If i remember correctly, it didn't.  It just pitched, being symmetric.

The shuttle does because the pad is oriented such that it needs to
roll to be headed the right way.  Thetower was set up for engineering convenience 
and the apollo just pitched after it cleared it.  The shuttle needs to 
do more, 'cause the tower is in the way for it.
