I'm not so sure governments all over the world would agree to participate in a global drill just like that, especially not during the present economic crisis. *Maybe* the WHO did deliberately overplay the threat to see what kind of response there would be in the event of a more serious outbreak. But it's not just a game. The swine flu has already cost a great deal of money. There's also the psychological impact. I'm sure Mexican tourism will be affected for years to come.
