I think there was more to it than that. The trial seemed to stop for two days after a mistrial, but Dewey made a cryptic post each evening, suggesting some rumblings were happening beneath the surface.
I doubt that Dewey expected the settlement: Abd wrote on ECW that Dewey is angry at the outcome of the trial. And I understand it ..... after shouting like a maniac and throwing threats right, left and centre it's normal for him to be disappointed.
