I assume this means that intra-city place names aren't considered?
Another anomly is comparing "Moscow" and "Cambridge". Most places consider "Moscow" to refer to the Russian capital, but consider "Cambridge" to refer to the city in Kentucky. I would have assumed the UK city would get the win here, but the nuance is that when people use this name, they're almost always referring to the university, and not the town it's located in.
For the dozen or so other cities I tried, it all seemed right to me. "Springfield" and "Portland" in particular.
This is neat!
