The blood stoppage was a go-to Vince Sr finish, used as a way to get out of a match without having to give a disivive outcome and to prolong the series. Watching these matches years later, I agree it's one of the worst finishes, and I groan almost every time one happens. I'm sure even the fans of the time hated it. Basically it was a loophole that exploited the whole "the title can only change hands by pinfall or submission" rule
