Condition for inflation presented by Liddle

By the way, I have another question about inflation.
If the horizon was expanding at a much more slower rate than the scale factor, that means that the observable universe today is just a tiny part of the whole universe. When I say whole universe I mean the true vacuum bubble that causes the inflation, I not sure if that’s correct. It seems to me a bit strange to call a giant bubble of true vacuum the whole universe…
Anyway, what I would like to ask is if the multi universes theories came from this fact. Is our observable universe just a small part that stayed casually connected until now? Are there other parts of the true vacuum bubble that we still (or will never be), are not casually connected? Is this parts that are called multi universes?
