Reaching a defense multiple times in autonomous?

[Owen Sull]

So the rules say you get 2 points for reaching a defense during auto. They do not specify reaching it multiple times. For example, if a robot reaches a defense, then crosses it, then goes back to the neutral zone and reaches either the same defense, a different one, or on that has already been reached by an ally, does the robot get 2 more points or is 2 the maximum?
