a ROBOT causes one (1) of their ALLIANCE’S BALLS to cross completely...

if the blue team pushes in a red ball it shouldn't count as scored but there should be a possession penalty on blue. Key word in bold above.

There was a discussion about this earlier where a team pushed an opponent into their own ball forcing it into their low goal. There was a direct action by the scoring alliance in that case. Here it seems the question is simply an opponent doing something that they shouldn't be doing.
