Not really, Woodward also said that he told Fitzgerald he may have mentioned Plame working for the CIA when he talked with Libby. That means that Libby stating he learned of Plame from "journalists" could be accurate.
Remember, this investigation has been going on for quite some time and Woody didn't testify until last week. Sure he told the truth now, but where was he years ago? He let the media skewer Libby and Bush's aide (drawing a total blank at the moment) for months without so much as a whisper in their defense.
He may have even showed up on talk shows discussing the subject as it relates to the inconsequential infractions of the Clinton White House.

Geez, brain fart!
