The glossary is there only to provide the narrow meaning of particular words or phrases, not to define when, where, and how a particular word or term is used within the rules. So I'm not surprised the glossary doesn't go into the details of when sweeping applies or is a DQ.
Some common sense needs to apply within the context we're discussing here: a pistol with a bullet stuck somewhere in the barrel. Once the pistol has been shown clear (mag out and hammer dropped confirming there's no live ammo in it) then one is free to take it to the safe area and manipulate it however necessary to fix the problem.
