Hi Jimiiee,

It was drew without any consideration for the enormous previously existent details at this area. It collided with all the parks and green areas that exists.  The residential area was/is already depicted by the footprint of all the existing buildings. The removed residential area had no name and a tag "level=-1" (?!?).

To see a self-explanatory (and useful) feature area at the same place place see: https://www.openstreetmap.org/relation/6528455
