It is a cataloguer's determination made under time pressure rather than a scholarly one, and it is weighted accordingly — but it is specific, it names its diagnostic features, and it can now be checked against the catalogue it cites. Note that the page is publicly reachable at the URL above; the house's own site search does not return it, which is why an earlier search of this archive recorded a false negative."
