If you get it, you can win with an extra point if you score a touchdown on the next drive (if you don't then the whole thing is moot). If you don't get it, you can still tie with a two point conversion on the next drive. Gives you a better chance of winning overall than going for one both times, where all you can do is force overtime.
They got it, but I really need someone to explain to me the thought process of going for two there. If you miss it, and somehow happen to score, you’re forced to go for two to just tie. Kick the point and you can tie or go for win if you score again
