It is. The broader/narrower relation in SKOS and similar contexts is specifically related to retrieval, with the relationship between the thus-annotated terms being that any item retrieved via the narrower term _should_ (as I understand it, this is not as strong as _must_) be one of the items retrieved via the broader term.
Thus 'bank' is a broader term than 'bank account', even though it is obviously not the case that a 'bank account' is a more specific type of 'bank' -- this is not the logical subClassOf relationship, and I think it's not even necessarily a partOf relationship.
We can be collectively reassured, therefore, that using SKOS would not deprive us of things to argue about.
Best wishes,
Norman
