My view is that the book was written useing the orginal shooting script because they needed the thing done for the orginal december 08 release date. Meaning that the fall and winter redits never get into the book version of the movie
Actually the novelization wasn't commissioned until late last year. ADF's website chronicles a bit of his challenge - he wrote it, apparently, in the month of February 2009 after a screening of the film for him in January.
