isn't it one or the other? If you take the overage, you don't get the sub.
Sometimes there is overage available between the trips that doesn't overlap with the trip in conflict, even if you opt for SUB. But if the trips overlap, you can't take overage and get SUB. At least that's how I've always understood it to work.
