In this case you would get a proper, filled area, because the area has a 
cat. Querying the exported vector would give you all the info for that 
area that you would also get in grass with the original vector, no 
information is lost.

Boundaries in grass usually don't have cats, and if they have, they are 
not used for linking area attributes. In grass, only the centroid's cat 
is used for linking to area attributes.
