I think you take the Zmax value from the console and enter it for both the third value behind "ORIGIN" and for "HEIGHT". The overviews I made that way certainly didn't show any strange behaviour.

However, I have seen some where you wouldn't see players moving in overview mode because their icons were moving below the "surface" of the overview. And on some other overviews, I saw the icons (which look a little bit like "dots on sticks") float high above the map overview, so to speak on top of extremely long "sticks" - even when players moved at ground level.

My guess would be that in those overviews, the overview maker screwed up and entered a different HEIGHT value, not the Zmax reported in the console.
