You're welcome!

Yeah, there's an overarching principle called "one feature, one element" (https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element) which means that for any object in the real world, there should only be one OSM element representing it. So Watson cannot be both a township and a village.

Caledonia is different because there are actually two Caledonias, the charter township (https://en.wikipedia.org/wiki/Caledonia_Township,_Kent_County,_Michigan) and the village (https://en.wikipedia.org/wiki/Caledonia,_Michigan).
