I think it does, but I find it unlikely it will reach any fine cloth shops. I once saw a polyester cloth at a tailor in Aqaba (Jordan) with a selvedge, which imitated a classic English selvedge. In regard to the H&S, I don't believe an "and" indicate much. Variation in logo is possible.
However, we should not dismiss the special joy and quality of finding a suit or jacket in a lovely lenght of cloth instead finding an appropriate piece of cloth for a jacket or suit we have in mind ... I think this thread demonstrates it.
Very good advice from zbromer.
Later in your bespoke life, bringing cloth to the tailor, which you want to have made up in a certain way, is more fun and rewarding than just picking from the tailor's cloth books.
