Does anyone understand this pepsi commercial?

-http://www.youtube.com/watch?v=EX0fmBHiZy4yes , the radio is playing a song about to rivals or enemies be friends and quit feuding . so the coke guy tried to see why the pepsi max guy likes pepsi ..so he tried some .. then as a friendly gag as a friend might do when a person is doing something you though you would never see ..in this case a coke guy drinking a pepsi max.. then the the coke guy realizes o- crap this could get me in trouble. The pepsi guy did this just to get back at a rival? then they start fighting and end up flying out the window. It is saying pepsi got the best of coke this time. The morel of the commercial is if a biggest rival coke can try a pepsi .. why can't you try a pepsi..
