Just a quick swipe fries any nasties that may have gotten on the mouths of the bottle. Never have I had an infected bottle using this process.
Flaming the mouth of things has always been a mystery to me. It was practiced a lot in science in regards to aseptic technique. Unfortunately its kind of a flawed procedure because while that flaming of the mouth kills anything present on the mouth, it also expands the air inside the mouth of the container (bottle). When the bottle cools, a vacuum is created sucking air back INTO the bottle. If you've ever added hot wort/water to a carboy and after shaking capped and you hear that sucking sound when you let go, its the same principle.
When I was in college (1999-2002) it was funny to see the techniques recommended by the different professors. In general the older micro profs would flame the mouths of test tubes, while the newer ones never bothered. Flame your sample loop, not your container!
