I'm sure that's what he means. In simple terms, there's no corner where
spaces touch diagonally. Spaces have an edge in common, or they don't touch
If you want to get a little more detailed, you can prove that there can't be
any corner-touching if there's no place where more than three spaces come
together. And with hexes, they don't.
