His claim was that the NSA had issues in the past getting encryption devices certified for use in unclassified environments because NSA controlled the certification process for classified encryption algorithms (which were themselves generally classified), but NIST controlled the certification for government use in unclassified settings (and these algorithms could not be classified). The NSA wanted to be able to use an existing algorithm in an unclassified setting. As the article does point out, Mr. George stated that the algorithm was intended primarily for their own internal use and user should be able to use any P and Q, though they needed their own P and Q certified for their own use.
Later on in the presentation he states that the P and Q were both non-deterministically generated random numbers. He states that the NSA has office devoted specifically to producing random numbers for their own use, and they just got the P and Q from there.
Whether or not you believe this claim is an entirely different and reasonable question (there's no real way to verify it), but why bother quoting him if you're going to selectively quote like this? If the P and Q are in fact purely random as Mr. George claims, Dual_EC goes from being a grand conspiracy to just a slow, crappy PRNG. I think selectively quoting to make this guy sound more sinister makes it look like the author wants it to be a grand conspiracy and just undermines the argument.
Btw., the entire presentation is worth watching if you have time - he goes into the history of DES, espionage between the US and Soviets, getting cryptographic equipment working in tanks, etc...
