Yes, there are reasons to allow two pads with the same net to overlap.
I create boards that have to accommodate a large variety of wire sizes.
 Since you cannot create a pad with multiple holes in KiCad, I need to
be able to overlap the two pads to conserve space and to meet my wire
size requirements.
