I figure that this will give the brakes time to cool since the pad isn't always applying pressure like it is when "riding" the brakes down.
This is what you're supposed to do.

When you ride the brakes, you have to continuously apply more pressure to get the same braking effect. The more they heat up, the more pressure you have to apply. The more pressure you apply, the more they heat up, etc.

Eventually, they fail. If your hill isn't long enough to make them fail, you're still wearing them faster than you would be if you were doing it correctly, using a firm pedal until you're somewhat under speed, then allowing yourself to coast with engine braking down the hill until you NEED to brake again. You don't necessarily have to go over the speed limit, but noone would fault you for going slightly under, if that's what it took to maintain safe braking ability.
