If they're not hard to wire serially, it shouldn't be that much of a problem to wire them as XOR (of course, you need a 3rd wire then).

In fact they may originally have been wired XOR. All it takes to turn XOR switch wiring into AND switch wiring is one faulty switch contact, or one blown or broken wire.
