I think the others have answered the question as far as how reverse okeetees have been created - by selectively breeeding amels that have no relation to okeetee stock.
I know Howie Sherman has produced as least one "legit" reverse okeetee - an amel from locality okeetees. I'm not sure how much he's pursuing that project, or what he's going to call it.
I would have to think that at least some people have bred an okeetee to a reverse okeetee. I don't think the "wide border" thing is as predicatble as some people may think. Okeetee X okeetee breedings can make offspring with normal thickness borders (as well as the thick borders that you'd expect). The same is true of reverse okeetee X reverse okeetee breedings.
From what I've seen, pattern characteristics like unbroken striping, border thickness, motleys with perfect circles down the back, vanishing pattern, etc. are not as predictable as simple recessive genetic traits.
For example I bred this male reverse okeetee (top pic) to this female (second pic - snake is in shed) last year. They both have wide-bordered blotches. Here's a pic of one of their offspring from last year (last photo, which I took today). Although the snake has some awesome orange coloration, its white borders are normal (perhaps even thinner than normal).
So while I think you might get some nice normal-appearing offspring from an okeetee X reverse okeetee breeding, and a few "keeper" normals with wide borders, I don't think it's the sort of thing most breeders would pursue, due to a lot of "by product" (normals that are het for amel and not worth much) and the lack of predictability in making a wide-bordered normal snake - especially when brightly colored okeetees are out there and they look pretty sharp whether they have wide borders or not - and the same can be said for reverse okeetees.
