After import with v.in.ogr, overlapping parts have a category value set in layer 2. If you want to get rid off all overlapping parts, check with v.category op=report if any centroids still have a category value in layer 2. Sometimes these areas can be cleaned away with v.clean tool=rmarea, sometimes manual editing with the vector digitizer is needed.
