It probably has more to do with how he breaks the balls than how he racks them. I watched Dennis Orcollo put a six pack on a guy by popping the wing ball every time, and he was pattern racking the balls so every rack would break about same as far which ball rolled where. It was a great advantage.
At DCC I think they were racking the one on the spot. If so, all you need is a tight rack -- similar to the Magic Rack result -- to make the wing ball dead.
It is really hard to blame a player for giving himself a tight rack. It is really hard not to blame a set of tournament rules that still racks the one on the spot.
