what is going on here?

is there an actual street number assigned here and mistagged as name?

or is it not?

why there is addr:housename without addr:street and without building tag?

Is addr:housename valid on https://www.openstreetmap.org/way/97419687 ? Maybe it should be name and addr:street should be removed?
