There's no difference between those stories at the microscopic level.

Um there's a difference at the level at which we decide to individuate and talk about large scale persistent objects like humans.

Um in my own view this is a terminological choice.

We can choose to talk in the three dimensional idiom, in which case I split.

Or we can choose to talk in the four dimension idiom, in which case I diverge.

Um I don't think I don't think it's fact of which of those is true.
