I agree with your point but the TDD comment tacked on at the end is wrong and adds nothing.

I don't think I've ever heard anyone speak in support of TDD say that the code is fine if the tests pass. The canonical process of TDD explicitly calls for refactoring after the tests pass. That step is crucial and lasts as long as it takes for the programmer to be satisfied with the code (e.g. 8 hours).

I also found no evidence in the article that there was TDD involved. Perhaps I've misunderstood either the article or your comment. If that is the case I'd gladly retract my criticism.
