I guess that the authors wanted to simulate a typical odometric system. Using the body methods is just too perfect and it's information that can't be accessed in a real model (well, may be available if you have a gyroscope on board). As Pioneer (the real robot) uses odometry for getting information of position (I guess, I don't have one), the model also use simulated odometry.
Anyway 470- 360 =110 degrees of difference between ideal data and simulated data is far too much.
