Not being a chemist, I can't say for sure, but I have to wonder if it could help spread fire laterally... I mean the wire passes from stud bay to stud bay, because it is installed within the wall. What would stop that fire from travelling along the length of that wire, and thereby travel laterally...?
I drill half inch holes for four-conductor speaker wire. If the wire were burning, there'd be too little air flow throught that 1/2" hole for the burning to go to the next stud bay. The small diameter hole would actually prevent the wire from burning. My guess is that it might go through a one inch hole with one wire in it, and I don't have the time to drill 1" holes when I'm running one wire.
