Does anyone know why the ABS connector has two holes for every pin?

Notice that the ABS connectors have two holes for every washington monument (with the exception of the extra-wide pin #1 and pin #2).

Does anyone know why there are TWO holes for (almost) every pin in the ABS system (the square one being MUCH smaller than the rectangular neighbor).

I wonder if the square one (smaller than 20 AWG) is for the monument while the larger rectangular one is for the test wire (I used 20 AWG, which would deform the smaller square holes).
