For what it's worth (assuming anything) : I had the same problem. Bought GF's first typology book, found a point that looked like a Squibnocket (going by his outline drawings), and he couldn't get it through my head that Squibnocket is a New England type that nobody finds in Pennsylvania because the culture that made them didn't exist here. In short, that the name refers to both the artifact itself and the culture that made it.
We had the same issue come up, not long ago, with a site (put together by a university department) that gave point types in (I think it was) Oklahoma the names assigned to similar ones made elsewhere in the midwest.
Occasionally you see pictures of Barnes (var. Clovis) points and Redstones that look like clumsy Folsom points. But they aren't Folsoms, because the Folsom people never got further east than around Illinois.
Where (IMHO) it gets outright silly is with points that are manifestly the same, made in the same era over a wide area. Nobody succeeds in splitting Clovis points into too many regional species, but the same point in North Carolina is a Hardaway, a San Patrice in Texas, and probably has other names in other places.
With Snyders points, at least there are distinct manufacturing differences between western and eastern forms.
Like any other principle, it's probably solid in the middle and pretty fuzzy around the edges.
