No, of course the pre-snap rules are rooted in advantage/disadvantage. What I'm saying is that we're not judging that when we see the foul like we do for holding or DPI. If Team A has 5 players clearly lined up in the backfield (say split end is off when he should be on), but the defense has no problem covering them or identifying eligibles, we're still calling it. If a player clearly flinches and the defense doesn't jump offside, we're calling it, even if there wasn't an advantage gained.
