If he did say it, it was a stupid thing to say considering how various choices line up and how creative ideas flow, I expect he probably said something like "I intend..." or "I'll probably try...", rather than "I promise".I'm not gonna look around for where I found it but I remember seeing it said he was going to do one route then the next.
Though honestly, it might just be my mistake and I'm remembering hearsay/wrongly
