On the web site I noted, there is an interesting essay on the song -- its quasi-Cubist approach was what attracted me to it originally (like Simple Twist of Fate). The later versions of Tangled Up in Blue are a good example of Dylan's perversity -- he seems to delight in wrecking some of the most perfect balancing acts he ever wrote. Ridiculous stupid lines mixed in with stunning new trains of thought. Really makes you wonder. I mean wonder in the best sense: like Michelangelo taking crayons to the Sistine Chapel, and doing interesting graffiti in the corner.
