OBB by my definition is the event that caused our observable universe to move into a state the latter evolution of which we are now observing. I did not explicitly reassert that it also very strongly seems to have produced a vastly larger part of the universe as well, since I said it already in my earlier post, but I don't think I explicitly ruled this out either. If I did I hereby recant my previous stupidity

It's widely believed to have created a lot more as well ("the uniform patch" or "the local inflation bubble", let's say LIB for short) of which OU is a subset. And from there you can't trivially extend the notion into there having been "more stuff" besides that which went into "creating" LIB. In other words, while it's possible that there is more something than LIB in the universe, this does not trivially follow from LIB's existence.
The dog, the dog, he's at it again!
