They probobly went more from the jedi ideals of the movies rather then the EU for a couple of reasons. One being that as Wheelman said, the casual starwars fan who hasn't read the EU and such would find it wierd if the jedi were like that and second, the movies are above the EU. The movies are what you should go to when you are making EU material because the movies are made by the creator of the Star Wars universe. You can't go wrong if you follow the movies...
