That was me. I was mistaken. For a given zoom level in Mercator projection,
a tile in an equatorial area shows more real-world area than in a more
northern or southern latitudes.

I actually confused the land area with scale: a tile in an equatorial area
has a smaller scale than in a more northern or southern latitudes. So land
area is inversely proportional to map scale.
