Resetting your save file won't alter that. The big thing people are noting about the Nameless event is that one of the times he asks you a question, that question becomes locked to your computer and cannot be altered.
So there's no need to reset your save file for anything (In fact that literally /won't/ do anything, haha), just whenever he asks you a question make sure you select the response you mean to select the first time, rather than expecting to be able to reload back and tweak things.
