It makes more sense for high end manufacturers, who want to sell expensive high end cables and make it hard for people to find and buy cheap compatible cables from anyone else.
Actually, I think its the other way. The confusing branding helps any low-end manufacture to do the least amount (cheapest) work to get something that looks like a high-end designation.
I don't think confusion can help them here. It helps to steer consumers towards less scary choice though, i.e. to the brand they trust.
Remember how in the Nokia days manufacturers of mobile phones all made incompatible chargers and data cables. Eventually they were hit with regulations. I think this is similar, but more advanced plot against consumers with plausible deniability.
