Although it clarifys, I really dislike that rule. If you are an arm robot, you probably will make the long deminsion your sides for front/back stability. So, your robot is 38 inches long plus several inches of pool noodle. The balls are 40", so assuming that your gripper is 25" long (in order to get past the center of the ball), your arm can only extend out of the front of your robot ~15". To me, that seems like it unnecessarily stifles some arm designs.
