It's not so complicated as you all are making it.

He simply wants the lights to be OFF when all four switches are in the down position.

In other words, if you run down the hall and flip all four switches to the down position, the lights will always end up OFF.

With an even number of switches, you will always have an even number of switches in a certain position with the lights off. Either four down, two down, or four up.
