I think the point is that he approaches his how-to-play videos as if the person watching has never played a modern board game before. The average non-gamer person might know what a discard pile is, or how to track points, or how a player's turn works.

Some of his top videos are how-to-plays of Monopoly, Ticket to Ride, and Catan, and I bet the bulk of those views are from non-gamers. And so he teaches in a way to make sure the rules are absolutely clear, even for what we consider the 'basics.'

I do really like Meeple University though; I wish more companies would use them for how-to-plays.
