Personally I find this a curious observation. I honestly rarely do TDD myself, but find it very similar to functional programming. Learning Haskell the big thing I picked up from it was top down design vs. bottom up design. What you describe is more akin to bottom up design. But I find TDD and even more so functional programming promote top down design which is the "strategic" approach. But it just goes to show any technique (including TDD) is not going to force you into good habits. This needs to be learned with experience.
