Err, I'm missing the point of my own point? You raise an interesting point, but I don't think TDD was what stumped Ron. It's not a simple problem to solve without a lot of thought unless you have the requisite background knowledge like constraint problems. TDD did however have him going round in circles, partly for the reasons you describe.
