So this is correct.

I can also add that the tag for NL Wikipedia page is also present (for all StSt I added to OSM), so to certain extent this addition of Wikidata feels redundant / double. But not incorrect as I just assessed.

Additional remark: there are 274 StSt in Eindhoven: are these to be edited in OSM in this fashion one at a time? That is going to be a lot of work. There are smarter ways to accomplish that.
