I'm not sure that update supports the claim of back tracking.

That was an update after the original piece (sadly not dated) but I think it's more sensible to assume that the update was written in response to Shift Jelly reading it and contacting him, rather than him being in discussion with them before writing it. Certainly I'd think it would be a very odd piece to write if he were already in talks with Shift Jelly.

The piece certainly implies that that there would be discussion around the project ("the details of which we’d work out privately" in relation to the functionality) rather than him thinking that people would just start coding and then come to him with a finished article so it reads more naturally as a clarification than something more radical.
