If a trailer has two valves I don't think they'd be for the two axles. If they weren't set just right for each truck, the axles might not carry the load evenly and you could be overweight on one.
I used to have a truck with two ride height valves, for right and left. It was better than most air ride trucks at keeping an uneven load level.
