The coordinates have to be in 3D as there are height elements, the buildigns are all texture mapped and the scaling shows that they are done the same way any item in 3D is texture mapped.
You could do this simpler with a non-3D engine but it wouldnt give the same feeling as when buildings and such that stuck up off the ground became bigger, the perspective of them wouldnt change.

Basically, the idea with 3D is that you have textures that are static and then you change the way they are mapped by manipulating the polys they are mapped too...
Its just a paradigm thing
