Osama's Islamic Two-Step

In that most recent audiotape, the full contents were apparently revealed in the past few days, Osama comments:

I have sworn to only live free. Even if I find bitter the taste of death, I don’t want to die humiliated or deceived,”

What about all that stuff about shahids dying the glorious death with the expectation of 72 virgins in Paradise? Is this a step back and a realization that he's not so much a martyr but a mass murdering bastard who conned lots of other fellow-travellers into killing lots of people with delusions of grandeur in the afterlife?
