SBR universe is a different universe. the meteor containing the stand-producing bacteria/virus landed in the US in SBR (where it animated the land, becoming the Devil's Palm) and greenland in the original (where it was found and some of it made into arrowheads). there's no Pillar Men and no Stone Masks in the SBR universe*, and pretty much the whole point of valentine's power was to show that the jojoverse is an expansive multiverse.

* since Cars never died, being immortal and all, if it was the same universe just with a reset timeline he'd be in each successive one and make the stone masks each time.
