And this is of course the way these Muslims think. Dates, anniversaries.... as well as the mystical number 19 from the Koran always show up in their plans. That's why this Sunday as a target date in New York City makes sense. October as the 10 month + the 9th day gives you the "magic 19" of the Koran.
And don't forget there were to be 19 bombers...
That does not discount the possibility that this is another "lets yank the american's chains" sort of joke someone cooked up for Romadon..
