Yeah, well. Maybe the grid can be moved more closely to the ground.
I get the impression that it's at that height to raise it above the elevated parts of the terrain - some (at least) of which are viable squares to stand on.
For example,
here. Lower the grid, and the guy on the right would be standing on half a square. Presumably, the grid gets placed just high enough to appear above any reachable square. (???)
I guess that getting it to hug the terrain (i.e. not be flat) would be harder, and not without its own issues. If there are going to be graphical issues, I think it makes more sense to go for the clearer, simpler abstraction - flat grid above terrain.
