I was interpreting it as the "coordinate frame" flips. That a device "below" (meaning above on a now inverted robot), would be considered as "above" the bumpers and thus not be legal to use to manipulate balls.
Why the heck are they using "" to explain anything I have no idea.
I took the line:

However, it must be noted that the ROBOT rules are defined in reference to the coordinate frame of the ROBOT when it is standing normally on a flat floor.

to mean that if it's standing normally on a flat floor, that is it's defined coordinate frame. So that when the robot flips, so does the coordinate frame assuming that the robot is now standing normally on a flat floor.
Maybe I'm reading too much into it and the refs have to keep a close eye and keep count of how many times a robot has flipped to determine what the "top" and "bottom" of the robot is.
