Hello Patchi,

The reason is that user yoann_immergis created a duplicated way with these tags before. See

https://www.openstreetmap.org/way/1419959614/history/1

In my change I deleted this superfluous parallel duplicated way and merged the new tags which this user had added in changeset https://www.openstreetmap.org/changeset/169952769#map=16/44.65934/6.63488&layers=VN. 

So I'm sorry, I'm not able to answer your question. If you really like to know we need to ask user https://www.openstreetmap.org/user/yoann_immergis

I asked him in his changeset to comment here.
