There's a reason for that. If you look at the rules of formal logic, you'll find that 'AND' has a lot of the same properties of multiplication. It is associative, commutative, distributive and idempotent.

I'd highly recommend some study of formal logic and/or Boolean algebra to anyone who writes code. A little bit of Boolean algebra can go a long way in simplifying complex conditions on branching statements.
