He has done this for years, Becky. Years! I remember a famous hybridizer telling me about him 10 or 12 yr ago. At the same time, the Salters were doing the same thing. I don't know if that's been resolved or not. I don't care enough to do the research.
I strictly buy cultivars from hybridizers I have met over the years. Being in FL, it's pretty easy. It is especially important since I am forced by my location to use totally evergreen daylilies. I don't like playing games with my money.
