If by "Hermes/Shengdu" you mean Shang Xia, no, their garments, bags and scarves are entirely their own and make no reference to Hermes. the workmanship and detail work, especially in their garments is amazing. Something one so rarely sees these days.
Their boutique is across the street from the Sevres boutique. I went in expecting to be underwhelmed, but I left very impressed. If you are in Paris and at the Sevres boutique, you should check it out.
As for the Moscou scarf, H makes scarves that bear the same wording, ie, H for whomever. Sometimes it is for a charity, sometimes for the opening of a new store, that type of thing. If you check out the "special edition" scarf thread, you should fine several examples.
