So he must have been in on the negotiations only because of his name being on those patents, or his unique understanding of those patents or something to that effect.
I find it strange to see him talking to the Oracle lawyers explaining the patent situations in a 'we're selling you this asset with which you can attack google' mode, and to come out now and act all surprised and 'I hope I don't get dragged in to it' mode.
He should probably expect to get dragged in to it, most likely by Googles council as a witness for the defense.
If he presented it to Oracle in a way that 'made their lawyers eyes sparkle' that sounds like he presented it in a very favorable light (for Oracle and Sun) during those meetings, if he's going to be dragged in to it he will have to repeat his stance on why this is something that Oracle can do in court or he'll risk being sued by Oracle for misrepresentation during the meetings with Oracle if he comes down on the defense side with his point of view.
I really wouldn't want to be in his shoes, this could get very nasty. And it could damage the Java brand considerably.
