The original mapping on Bing was on the current Esri Clarity alignment. The current Bing alignment is the same as Maxar (and subsequently Esri). NoelB changed it from the old to the new Bing alignment.
I assume the old Bing alignment was skewed in this area. (The new alignment also better matches the British War Office Map)

Change to new alignment. The northern part of the island wasn't made more accurate.

Change of buildings to new alignment. The rectangular building was further adjusted.
Everything, especially the buildings, seem to be offset to the southwest however. Except from moving everything at once, it may be that Noel had a custom offset on. I would personally ask Noel what they think.
