I think it comes from an attitude about a different era of the internet as well. When I was young, I would expect most of the information about say a particularly weird house comes from the website of the owner of the house, or maybe a blogger who is into local architecture, if its on the internet at all. In that context it makes sense to try to query with what you think the owner would self-describe as (so like find out what the proper name of the style is, then query with that). If you come from an era where most of the stuff on the internet is people talking about or sharing the minority of original content, it makes more sense to query using terms that the casual viewer of the house would use.
