No that is a clever way of keeping the ball in place that 4183 also used, I don't know if they adopted it from us or if it was separately thought of but it works either way.

When a ball rolls into the robot through the intake the ball is rotating because of the roller so the ball pulls the tubing down and stretches to accommodate the ball. When the ball is on the other side however the tubing blocks the ball from leaving the intake, keeping it in the correct firing position and preventing the ball from rolling out.

It sounds really weird but it works really well.
