Did Daniel slip up and reveal something he wasn't supposed to?

[JoeM]

Was it well known that the wealthy business man, "John Doe" that Daniel played during his heads up challenge matches was Jerry Buss? On this week's second episode of Poker After Dark he stated that he played Jerry heads up.

That would mean that Daniel finished stuck around $493,000 to Jerry Buss...ouch..did anyone else pick up on this? Is this too much speculation?
