Weeks were spent in the iterative design process to ensure "these sorts of things" were physically impossible with the 254/968 pinch roller design. The mechanism was on a free pivot, such that the entire robot could lift from the floor by a significant amount (more than 1" I believe) and the ball remained in contact with the ground, such that a piece of paper could not be slid beneath it. For added security, at Long Beach, 968 added springs to actually push the ball into the ground with some force, beyond the weight of itself and the mechanism. I don't feel that any team with such a mechanism got away with a certain "way" referees were calling anything.
