I think that it does an intersect of (center or perhaps end?) points back
with the original layer.  In the some data cases, this selects additional
features.  I think that you found it worked correctly for non-overlapping
polygons, try it with polygons that overlap and you should observe the same
behavior I think.  This could perhaps be addressed by passing feature IDs,
JSON, GeoJSON or something else between the table and the Results tab.
