I think that WAY: 1286482007 is two adjacent buildings. The Eastern building is significantly larger than this footprint would suggest. Using alternate imagery can sometimes allow you to see the complete size and shape of obscured buildings. In this case the building is visible in ESRI with a silver roof. Using bing as the base (lower) layer with 100% opacity you can add ESRI, then reduce its opacity to x<50% and align it to bing. You can open this changeset in josm by pressing "J" in OSMCha.
