The whole rider is pretty nutty. Even on fairly mundane requirements he manages to sound a bit crazy. "I absolutely refuse to have a break in the middle of my speech. Once I start, I will go straight through." Presumably at some point he said he didn't want to take a break but someone stuck a break in the agenda anyway and he decided to declare his intention to throw a fit if that ever happens again. It reads a little like "100 ways in which RMS cannot handle the unexpected."
