Maybe he doesn't know how to turn the turret around and thought "fuck it, stick it in reverse!"
As someone who's spent bleedin' ages attempting a different rhino precision (to the stadium ring), I feel confident in saying that trying to land a rhino on those containers would be nearly impossible due to the rounded top. The issue is not with distance or height, it's just that there is not enough room to be able to stop the rhino properly, even if you get a brilliant kick and go straight in the air and land directly on top of the container it will still bounce you off or you'll agonisingly slide off.
Realistically the sunshine autos BB seems to be the most realistic landing spot. It's a great find though all the same.
