Should the series be rebooted, it would be set in the same multiverse
It would start in a new reboot "Earth Prime", but the multiverse itself would be the same one we all know and love, even if they don't go to the same worlds.

Their Earth Prime isn't our own.
If they ever traveled to our world they'd be surprised to find themselves in a universe where their exploits are actually a TV show in this world.
