It's another instance of buildings housing street-level addresses. Check the photo. You kinda want to put the building name in the address... but it ain't necessary, and it's counterproductive.

Example: as it happens, there's a management company, and Companies House (not a valid source for OSM: Crown Copyright!) contains all sort of chaos inside just one listing:

* <NUMBER> Elizabeth Jennings Way, Woodstock Lodge, Oxford
* <NUMBER> Woodstock Lodge, Elizabeth Jennings Way, Oxford
* <NUMBER> Elizabeth Jennings Way, Oxford

https://find-and-update.company-information.service.gov.uk/company/05352457/officers

For a different company, there's an even wackier

* Woodstock Lodge, <NUMBER> Elizabeth Jennings Way, Oxford

https://find-and-update.company-information.service.gov.uk/company/09499441/officers

Those are just real-life examples from one searchable source, demonstrating how chaos ensues at the intersection of this settlemant pattern, Royal Mail PAF-style addesses, and OSM's Karlsruhe schema. We can't import from that source, which is fine since it's a mess.

Anyway, I think omitting the building is Probably Right here as far as OSM's schema goes. Being located inside the building outline should be enough of a hint to routers about where the address nodes actually are, and the short interpolation way fills in the odd-only addresses cleanly.
