not a good example IMHO. I see it like this: surface is the real
"surface" = a very thin layer, say infinitely thin, like the surface
of a road.

Landcover would be road (or highway) because it comprises also the
other layers of the street (the metre below the surface). This might
not yet make sense to you in the case of a highway, because
landcover=road/highway is implicit in highway=xy.

+1
