Personally, I don't see it as much of a deal, and if anything it kinda makes sense. While the "flashback" is mainly intended for the human playing the game, in-game it's also our character "remembering" an event from the past. Personally? When I (in real life) remember something from my past, I don't have a clue what I was actually wearing at that time. My mental flashbacks don't come with photographic memory of what clothes I was wearing that day; if anything, my brain does exactly what this game does and just kinda places me as an observer from the present day re-witnessing the past event.
