Well, this is probably a good exercice in boolean logic - which is 
something very important in CS.

But my question (sorry, it may not have been clear) was more along the 
line of : "why do you worry about identity in the given snippet ?". 
Rebinding a name already bound to a given object doesn't affect other 
names bound to the same object. So in this case, multiple assignement is 
perfectly safe.
