  If you think about it, that's exactly the correct behaviour.

  An inverted union is everything outside the union. Now the "outside"
is everything that was "inside" the union. "Outside" doesn't have any surfaces
in it, but it's just empty space. Inverting a union implicitly "removes" all
the inner surfaces (because they are not inner anymore).
  Now if you invert this object, you get an object which is everything that
was "outside" the object. That is, the original union with the inner surfaces
removed.
