How does 469 not violate <R19>?

[Radical Pi]

I have a little rules situation to put forward.

Suppose there have been 2 balls scored. 1 of them has passed through the chute switcher and is on its way down the main ramp. The 2nd ball is on the ball return chute. A 469 (or any similar bot) driver sees the defender speeding to block the active chute, and, while the 1st ball is still on the chute, switches to the 2nd chute. For the period of the chute switching directions, does that turn their return system into an active mechanism?

If that were true, what if a bot drove up on the bump and put themselves up against the 469 ball return. Since they are on the bump it is legal to touch out of the bumper zone. If a ball were to be caught on said chute, would an attempt to bypass the block be considered an active mechanism above the bumper zone manipulating the balls?

P.S. congrats to 469 for designing a robot that has yet to have an effective counter-strategy devised against it.

Also,

If a strategy was employed to try and block 469 at the tower, they have the ability to score from the middle position, so having that, they really don't have to attach themselves to the tower if they find that a robot could effective block that strategy. They could become an effective middle position scorer.

looking at the speed at which the chute can be activated, it would mean taking one of your bots completely out of the game to block the entry to the tower just to prevent 1 robot that is still a very effective scorer from activating their amazing mechanism
