The ball has half of it's volume on each side of the midline. This means you do not need to cross it to move it out of position. If the first thing you do in the autonomous mode is simply nudge the boulder, you run very little risk of making transitive contact through a boulder since you will not be touching the boulder by the time the second robot makes a grab for it.

In addition, if you make first contact with the boulder it would be the other team incurring the foul for contact, not you. If your robot is touching a boulder and the 2-ball auto team tries to intake it, they would be making transitive contact through a boulder with you, not the other way around (you are not making transitive contact if you get there first).

In a way I could see this becoming a new kind of canburglar arms race, where teams try to touch the boulder first. From the way the rules appear to be written it seems that if you touch the boulder before the 2-ball auto bot tries to intake it, they're making contact with you and they will be fouled. If they make contact first, then you nudging it will be considered a foul. Thus, the speed at which you can get to that essential (for a 2-ball auto) boulder will become more important as the stakes get higher.
