I've never ridden a tri bike, But I can't imagine having the hips rotated that far forward at all relaxed . It certainly puts you in a low position with your back horizontal and gets the hips far forward for the aero bars. My road bike puts me at a 45 degree back-angle when I'm on the hoods. Now that's relaxed.
If that tri position was all that relaxed, US Postal/Lance Armstrong would use it for more than just the few time-Trial stages in tours.
