That is explained on page 85 of the Pickaxe (113 in my PDF edition):

   "In older Ruby versions, the result of the assignment was the value
   returned by the attribute-setting method. In Ruby 1.8, the value of
   the assignment is always the value of the parameter; the return
   value of the method is discarded."
