Instead of a flashback or flashforward, they're just doing flash sideways'.

Incorrect. It is an alternate reality. Showing you what would have happened for shits and giggles makes no sense narratively, especially since it's the final season.

Blowing up the island with a bomb caused an alternate timeline that stems from that moment onwards. I'm pretty sure the producers confirmed this.
