Here] and the map of the multiverse is just a rough idea, it's not really like that. Just creating those physical and meta-physical boundaries is separate, Each multiverse has its own metaphysics and when the Earth has infinite universes[multiverse], then each earth has a different variant from the other earths, If you read the multiversity comics, the Sandman universe is also in the DC story, the cosmology cannot be separated

Multiversity tells about the existence of a real world on another earth but a fictional one on his own earth [
Here ]
Sorry, I'll explain again. 1 Earth = infinite universes [ multiverse ], 1 EARTH is different from other Earths, omniverse is a collection of different Earths. The variety of earth and other earth is different, The story is also different
