I know you addressed this question to Chris, but while you are waiting for him to answer...

It is because with the twisting action of the knob, the driver intuitively thinks of rotation as a clockwise/counterclockwise thing (which is independent of the orientation of the robot) rather than as a go_left/go_right thing.
