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.

This is untrue.

Want proof? Set it up so that the lights are off when all four
switches are down.

Now turn one of the switches upside down. The lights are still
off, but now there are three switches down, and one up.

So do you wander through the house flipping switches over in
electrical boxes on a daily basis?

Do try to pay attention here. The *only* purpose of that statement was to point out your error.

If he wires it up so that all four are down and the lights are
off, and LEAVES THEM ALONE, then the lights will be off with the
switches in three states:

1. Four down.
2. Two down.
3. Four up.

Yes, of course -- but that's not what you said at first. You said
"with an even number of switches, you will always have an even
number of switches in a certain position with the lights off" --
and that just is not true. It's quite possible to have three up
and one down, with the lights off.
