Yeah, like that.  Notice the work they have to do to make a
not-really-random or only partially-random source flat, unpredictable,
random.  What they do is probably overkill -- nobody on earth could
detect a deviation from randomness if they did only half of their
folding and retransformation with crypto grade prngs, but it is still a
pretty reliable scheme.
