Nope, still not buying it. At what point do they replicate into two beings? If you travel to and fro you are taking yourself with you - you are not leaving behind a clone to carry on as if you were still there. Besides, in this case if you're saying that they went to the future, saw the mess being created, went back to the present and then carried on, then they would do that knowing what a mess was coming and therefore how to avoid it.
In physics, there is a theory that states every decision we make causes the universe to perpetually split creating infinite versions of reality.
I know what you're saying, that if you went into the future you wouldn't meet yourself, because having time travelled, you remove yourself from say, 2023 and if you arrive in 2053 there'll be no 'you' since you didn't live those 30 years.
However, your decision to jump forwards is one choice, the other is to remain in 2023. Thus, there would be an alternate 2023 created in which you never time travelled and this is the one in which you could meet your future self.
In essence, you'd arrive in a 2053 different parallel universe where you never time travelled and your future self is there. In your universe, what you say might occur. So time travel can be thought of as jumping across 'parallel tracks' of identical universes. If you left at say, 2pm and went back to 1pm to shoot yourself, you could die in that universe, but not in your own since it would paradoxically undermine your existence. But in an identical universe, it would seem like you shot yourself since it all looks the same.
I like to think of it like playing two identical DVD's of a movie. If you leapt from one movie into the other, you can visit the past or future of that movie, but not yours. And because they're identical, it would seem the same, but there'd be two of you, you from movie1 and also you in movie2.
