say you own "3 acres of land" you can build a HUGE mound of dirt on it, its still 3 acres, you could not sell it as 4 acres because of the extra Z height you added.
And thats where the word ASSUME comes back into play. I dont need a fucking lesson on area. I know.

The devs could have very well calculated the amount of traversable surface, instead of just the square grid, when getting the numbers to describe the game land.
