I am definitely unsure if Craig is Satoshi. However, I think Ryan's point is that it would take significant evidence that someone else was Satoshi to convince him that CSW is not.
Frankly what difference does it make? Who Cares? We know it's someone within the BCH community Because they are the ones following the Satoshi White paper. thats all that matters
It's an interesting and fun mystery, regardless of its significance =). I'll once again shamelessly throw a plug for my favorite book on this story: Digital Gold by Nathaniel Popper.
