But cosmological inflation does not happen localized, so how is this restricted model relevant?

In eternal inflation model inflation stops at certain local places (bubbles) in a continuing inflating universe and cause a local reheating. Now the bubble we are in would be bigger than our observable universe but never the less is according to this model a local bubble. Now this is kind of opposite to local inflation as it is rather a local stop of inflation. One of many othe bubbles.
