This is plot logic not theoretical Physics. If the multiverse is truly infinite It is too big to affect. No conclusion possible.
So, there is a limited number of them and they tend to snap together if they ain't different enough.
Far enough out in space where nobody is doing anything or watching too closely they have all snapped together. If the sentient beings are planet bound then so is the 'verse.
Think of the multiverse as rubber with some, perhaps all, owing their existence to a "God" who is forcing a difference.
In the Demonverse God does seem rather protective of the demons and clearly believes he needs them to hold on to his universe. In the Infected 'verse a single vastly intelligent being is responsible for the infection - and fights any attempt to remove powers. That must be how he holds his universe from merging back.
Then there is the adversaries attempts. A 'verse with no population looses its identity. If the plan is to bring back ancient gods then the fewer 'verses stretching the rubber, the easier it is for them to squeeze in one of their own. This also explains the Adversaries lack of overall co-ordination. If they did things the same way then the groups in different 'verses would snap together.
In fact it follows that the Adversaries HAVE spit off a 'verse - The mirror to the Young Ancients 'verse where some have been convinced that killing as many as possible is the right thing to do. I would guess that was why they lost out in the first place. Ultimately sufficient evil leave a 'verse with not a lot of character. One trashed wasteland is much like another while evil slave owners don't encourage individual expression. Still - maybe they have worked out that evil won't do a 'verse damage if it's exported.
So my main points. 'verses are mostly planetary or solar system size (with presumable other 'verses based around occupied planets of other stars), It takes a God real work to split one off and keep it discreet, and there are not a lot of them - Tens or Hundreds at most.
