Honestly, it doesn't look very clear from those replays. It seems likely that he tagged him, but I can see why the ump would say he didn't.
Oddly enough, replay wouldn't have helped much.
Frankly, I think guys swipe tag way too much. Especially at home. If I'm the catcher, from now on, I leave no doubt that I tagged him. Maybe I leave a bruise, but the guy was tagged.
