Unfortunately, it doesn't.
I have had three long conversations with TSA HQ and the bottom line each time is, an agent on the ground can basically change any written rule they want on carry on and check in to make it stricter if they think it is a good idea at the time. Essentially, I was told they COULD make me check my regs if they wanted to even though it is IN WRITING I can carry them on. Typical gov agency actually.
