1 - It was introduced by a novice mapper, presumably as a typeo.

2 - Nikolas von Randow fixed it about 9 months later, presumably with
some kind of QA tool (maybe just a overpass query).

3 - Another local novice mapper also edited it, and fixed another issue
at the same time. Presumably noticed via a rendered map.

Before criticising the mapper, it should be noted that it was a novice
mapper and the existing building data in the area isn't of great
quality anyway. This wasn't a regression. And accidents happen anyway,
I've done a similar thing via StreetComplete where I entered the house
number in the building levels quest.

The big companies doing QA on OSM data (Mapbox and Facebook) have a
high focus on vandalism. They are trying to stop "Jewtropolis" from
ever happening again.
