I think you overcomplicated the explanation that you ended up confusing yourself.
Also note that Abe(N) is being pretty daring here: planning to deliberately break symmetry with their "doubles," which is something he never wanted to do before. In all likelihood, this is because the universe continued to exist with no apparent ill effects after the paradox phone call incident (where <PERSON>'s phone rings both the "first" and "second" times through a particular day) somewhat earlier.
You'd already called Abe(N) the one sleeping without being disturbed in a previous paragraph and in THIS paragraph you are saying it's the one who was awaken by the kids and wants to punch <PERSON>. Besides you added that N for no good reason at all, it only overcomplicated the explanation; the other time travels don't matter if you are explaning <PERSON>'s plan scene.
Dude... then for some reason you started calling them (N-1') O___o what the hell were you trying to do??? You used 3 different names for the same guy: Abe(N+1), Abe(N) and Abe(N-1'). If you read what you wrote like 5 times you end up understand what you meant but... please you SUPER overcomplicated it all.
We see later in the movie that you have people popping out from other possible futures in the present, so each time they travel to the past and break symmetry in an important way... you have two possible scenarios: 1) the original timeline deletes itself from existance and the new timeline is the only one that keeps existing 2) all possible timelines are real in some kind of multiverse like in the MCU.
We know even later in the movie that the MCU alternative doesn't happen, there's only one reality if you break symmetry... the original timeline disappears. The only way that the original timeline keeps existing is by avoing breaking it. 283
Remember... boxes can be used ONE time. That's the ONLY way there can be 3 Aarons from 3 different realities at the same moment.
<PERSON>'s plan would break symmetry in really significative way, therefore there'll be two <PERSON> and two <PERSON> existing at the same time forever.
Original <PERSON> is awaken by the kids, goes to Original <PERSON>'s house and makes the Punching Pratts Plant.
Friday 3 am: Original <PERSON> and Original <PERSON>, after punching Pratts, get into the boxes. Thuesday 5 pm: Original <PERSON> and Original <PERSON> get out of the boxes and prevent the kids from waking New Reality <PERSON> up.
Now you have the Original ones and the New Reality ones. How the hell can they get rid of the new reality ones?
If the New Reality ones go and do business as usual... nothing would change because they wouldn't break symmetry.
Friday 8:30 am: New Reality <PERSON> and <PERSON> start the boxes and go to the hotel. Friday 3 pm: New Reality <PERSON> and <PERSON> get into the boxes Friday 9 am: New Reality <PERSON> and <PERSON> get out of the boxes.
At end of the movie we see one new reality where there are 3 Aarons, 2 from deleted timelines and 1 belonging to the New Reality where 3 different Aarons exist.
You are right about <PERSON> thinking, in that scene, there are mutiple realities each time they break symmetry which end up being wrong.
OOOOOOOOOOOOOOOR (CAUTION overcomplicated crap):
Each time you use a box you create a new universe, but if that were the case then by just using the box once... you'd be creating infinite universes because in each new universe you are using a box again, which in turn creates a new universe in which you're using a box again and so on. Infinite energy... so this can't be the case. 844
