I think that they are supposed to be assymetrical to assist the 
"acceleration".  In theory, with the hole shifted to the front, the 
key is automatically going downhill when played.  Also 
theoretically... with a flat platform/punching, as you play the key, 
the balance point moves toward the player side of the punching and 
the key actually rises up on the balance pin.   I can imagine that 
the harder/thinner the punching/key bottom, the more likely this 
effect is to move from theoretical to actual.

How much this effect actually matters? Dunno.
