I assume you asked the GDC in a Q&A not some random volunteer.
Remember, even answers from the Lead Robot Inspector may change as the season progresses and they all come to a common rules interpretation.
I don't recall any such Q&A though.

I think your issue here is how the question is framed and (presumably answered by the GDC).

The answer you received appears to simply be addressing the issue that the compressor must be powered through the robot by the robot battery whenever it is operated, not that batteries cannot be changed.

The robot can only be powered by a single battery while in a match.
A match doesn't begin in the pit or on the queue or in a previous on-field appearance where pressure wasn't releaved afterwards.
A match begins when the field sounds.
