the GLR ref said it was to allow the intent of the game to be played out. that intent being to score ringers. you could get in front of the bots to block them, and you could unintentionally hit them. but if you made a significant attempt to push them or hit them while they did not have a tube, you would be penalized. I was a little shocked at this rule as well, but i did think it made for a more exciting game with higher scores all around.
