Until you mentioned it, Caleb, I wasn't familiar with Flush Brush or Doug Conn. But I just looked it up and watched Doug Conn's routine on YouTube. There are certainly similarities in the moves and method he's using to what I do in the 4 Ace Production. But it's something I came up with independently back in the 1990's and have been doing ever since. (I don't know when Doug devised his routine). In any event, I'm pretty sure that no one else has done or is doing the false cut I came up with for my version.
