Not universally true. Streetname signs in the Boroughs of Gedling and Rushcliffe actually may show the full postcode. Example here: https://flic.kr/p/9r747b <https://flic.kr/p/9r747b.> . This is both ground truth & authoritative for postcodes belong to (some) streets :-)
Secondly, OSM mapping is incremental. It is often possible to deduce the postcode applying to buildings on a street (basically all shorter ones with, say, under 60 addresses) merely from inspecting the postcode centroid. Adding the postcode to the street seems reasonable in these circumstances.
