That he seemed to be surprised they're ending his contract early in the articles linked. He said he'd be working concurrently on post, but was still up for SNL. I dunno what his demands were, but it sounds like they don't like that sort of thing over there. Basically, he wasn't planning on leaving the nest just yet, but they tossed him over the side anyways.
ETA: And I brought up Lorne because he has a track record of having a hand in other cast members' projects, however symbolic, leaving said nest. Myers and Carvey with Wayne's World. Spade and Farley with Tommy Boy. Ferrell and Kattan with Roxbury (bad example.) Fey with Mean Girls, and obviously 30 Rock. Just thinking that Killam leaving him out of the loop here might have had something to do with it.
