The terrain is not flat, it is actually a cube and the terrain can exist at the bottom, middle, or top of the cube. For example a 1024x1024 terrain at the middle would have to be put at -512 on the Z-axis so the actual terrain is at Z-axis = 0 coordinate.

I know this has already been answered, but here is a bad Paint image explaining it again:

The terrain block has some position, that position indicates the location of one of its corners (I believe), and the terrain stretches out from that position.

You only have the height of the terrain at some specific point, but in order to get the world-coordinates, you need to take that terrain height, and offset it by the z-position of the terrain giving you the \(z\)-coordinate.
