Few points: (1) Chaining rnd generators is fine as long as they are not correlated somehow. If there is any correlaton, the output may be weaker. (Consider chainig two exactly same generator as a corner case.) (2) In this case we don't chain generators; you would loose the speed of the integrated one otherwise.
