I think we're just having a semantic argument now; just because meta roughly means "above" doesn't imply singularity (you could envision a metametaverse above multiple metaverses). And the existence of a singular observable universe doesn't preclude the many-worlds interpretation of quantum mechanics or the accompanying "multiverse".
