As does South Carolina. This would give them four and likely give them an SEC Championship meet (and kill the Big 12's as they go from four to three schools).
The SEC schools are much more nationally competitive overall than the BIg 12's. The only teams that ever beat us for the overall national title are the SEC teams. Us moving east kicks up the level of that conference's western side, which we have long dominated at, to the level where their English side has always been. The SEC has been the class of English riding since they picked up equestrian and second place hasn't even been close.
