Ah, I see the reason why you don't see the value in moving it. Your name doesn't explain this at all. The name should explain which case (of the 3 cases) we're hitting. This kind of "what are the cases we need to handle" information is the most important thing for you to document in comments/names here, and it doesn't exist. Referring to 430 isn't enough, especially since I don't know where that's listed in 430.
