Haven't looked at your drawing as yet, but I think the Area property can be inaccessible if the hatch has a self-intersecting boundary.

Take a look at the attached file, after regenerating the hatch boundary's I found that the left side is composed of inner and outer polylines.  while the right side is composed of multiple hatch boundary's, in order to pull an area from a hatch it must be closed and one continuous segment like your example on the left.

Hope this helps
