Hi, thank you for the overpass query. I am the local mapper who is responsible for this area. If you take a look at the history of the node, the last change was from 2011, so it is so old that I can clearly say that we can change it with no doubt. The mapper who made this change first entered the steps correct (highway=steps) and then changed it to the wrong tagging, so maybe he was a little bit unsure about the correct tagging. Since then a long time has passed. So I just corrected it. When I will be there the next time, I will revise this area completely anyway.

Greetings from Euskirchen, Germany.
