Is it OK for others but not Arafat?

Although Toronto Star is one of the best papers availbale in Canada, it too, sometimes acts strange and idiotically.

The front page of Today's star has an article titled Arafat chooses own man for PM . Isn't it a norm that a president usually chooses his VP or PM? If yes, why is it so strange that Arafat has done the same thing? Or, is Arafat supposed to choose his PM so to meet Sharon's approval?
