Answered: <SG9> Violation?

Is what the robot on the red alliance did, in the link below in violation of rule <SG9>

The action that I’m referring to is at this link,
link text The team uses a flat piece to push two of the blue alliances mobile goals away from the other alliance and the blocks their path to the goals preventing them from using them to score.


There are no rules preventing this. <SG9> only refers to Cones, not Mobile Goals.
