Clinton is doing nothing but playing a PR game so he can say he can say he resigned and not have to say he was disbarred. It's all about spin. He is disbarred and chose not to fight it. It is a simple as that.
He was prolly afraid that after that glowing, read, illuminating, speech he gave at Georgetown, if he tried to fight it, the Court might reconstitute hanging for raw treason.
The game was over before resignation. Clinton's mass media fictional threat to fight disbarment from the beginning was the heart and sole of the plan. Who cares how he avoids it now? What sticks in the public's mind is his intent to fight it, and they will rationalize the outcome to fit their perception of that. And Clinton... knows it.
