The idea is you need to score a bunch in a short time. So making the 2 down 13-34 lets you go for 2 twice and score a FG to tie, and you're still afforded the opportunity to both make up for the miss and potentially even account for a FG down the line with later 2-pointers.

Once you give up on going for 2 later though, it makes very little sense to have gone for 2 the first time as you won't be able to recover from the other team scoring a FG.
