Hi!
This tags have been added automatically by JOSM-Russia-address-helper-plugin ( https://github.com/micronull/JOSM-Russia-address-helper-plugin ) after importing data from Russian Cadastre ( https://wiki.openstreetmap.org/wiki/RU:%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D1%8F/%D0%9F%D1%83%D0%B1%D0%BB%D0%B8%D1%87%D0%BD%D0%B0%D1%8F_%D0%BA%D0%B0%D0%B4%D0%B0%D1%81%D1%82%D1%80%D0%BE%D0%B2%D0%B0%D1%8F_%D0%BA%D0%B0%D1%80%D1%82%D0%B0). 
I used it to fix address of that building ( osm.org/way/1212516687 ), and most of that tags were not usefull. But i made a mistake, so they were not cleaned before uploading.
Thank you for having noticed it.
