It's simply marketing. Imagine visiting your local big box store and finding "Red Lady Banks". The ONLY resemblance to Banksiae is that it climbs.The rose actually provided under that name is Red Ribbons.

That kind of "marketing" has been used for many years. Have you ever encountered "Banksiae Snowflake" in nurseries and big box stores? It's Fortuniana. Monrovia Nurseries has practiced it for decades. Look at their tags and in their catalog on line. They have frequently renamed existing named cultivars so when you look for the plant by their name, you only find it in their signature green nursery cans. But, you can also frequently find it for significantly lower prices under the original cultivar name. QVC and other online and television retail sources have been re naming roses and other plants. All of their branded mini roses are already existing named minis, but under their names, they are "exclusives". That kind of marketing has been going on forever. When foreign roses are introduced in to other markets, they frequently are given names more specific to that market. Meilland renamed many Moore minis for the European market. Rise'n'Shine became "Golden Sunblaze". There are many examples to be found.
