I don't quite understand the memorandum [1] yet either, but it does say [2]:

    the fact that a person may be employed as a computer programmer and may use 
    information technology skills and knowledge to help an enterprise achieve its 
    goals in the course of his or her job is not sufficient to establish the position 
    as a specialty occupation. 

So, calling the thesis of the article "absurd and incorrect" is probably too early.
