personally I'm hoping it's timeline-hopping. that they are now on Earth-20000 or something. on Earth-19999 this future won't happen because it's they've witnessed the "possible" future of a different timeline, but they also don't prevent it for Earth-20000 because it already happened there.

Funnily enough Dragonball Z handles this exceptionally with the Trunks-Android-Cell Arc, because you think that Trunks goes back in time and successfully changed the past, but as soon as he goes back to his own time he finds nothing changed because he actually parallel universe hopped
