Still makes no sense because teams don't convert on almost 60% or two points conversions. I'd say kick the PAT to be down by 7 then if you score another TD and want to go for 2 to win, that makes more sense. Which when I've seen works more often than not.
I do love how he mentions if you have to go for 2 twice that it's likely due to no confidence in your kicker. Nebraska did this one time against Miami in 2015. Down by 16 late and unbelievably scored 2 TDs and converted the Two point conversion both times to send the game into OT.
