chaos and honey

is it a mistake or intentional that the ny times used in a headline today PLO and that the writer, steven erlanger, referred to arafat and his aides who canceled a trip to paris as part of the palestinian liberation organization. am i missing something? i thought they officially changed their name to the palestinan authority after the oslo accords. http://www.nytimes.com/2004/11/08/international/middleeast/08mideast.html?hp&ex=1099976400&en=4d6fdd75c8348688&ei=5094&partner=homepage
