One hypothesis put forward as to why the trajectory is flatter with longer hops is that they don't need to push as much on the BB since the contact is longer. This means that the initial point around which the BB spins is closer to the center of the BB, while regular bump hops push harder on the BB (and the BB against the bottom of the barrel), making it spin away from it's center mass when it is suddenly released. While the BB is in flight it would progressively start spinning around it's center mass, but that would cause the BB to slowly fly up while it stabilizes, resulting in a less flat trajectory.

I'm no physicist but I think this makes some sense.
