I agree it would be odd. I thought of it after a reporter commented that it was possible French intel was trying to get bin Laden to respond on video to prove he is alive. Since we have long heard that an attack would coincide with a video release, it just struck me as interesting.
Just remembered . . . 8/23 was the tenth anniversary of the official declaration of war by al Qaeda against the United States.
It is interesting, and possibly significant.
