Cathy, bless your heart for trying to protect one of our own :-) I wouldn't get too shook; I first heard that tip back in 2004 at my LQS here in the Midwest, and IIRC they said it was an 'old trick' at that time. This type of thing happens with tips sent in to places like Fons & Porter's too - I've seen multiple credits in their tip section a couple of times. It happens. Klue may have discovered it by herself; she just may have not been the first to do so.
Kudos to your eagle eyes, though - as quilters, we should always be conscience about where our patterns, ideas, etc. come from.
