I think it could make sense, especially after the events of Summer Slam, first being rejected by Team WWE and being replaced by Daniel Bryan. He could have been planning on costing team WWE the match the entire time. If you notice, the Nexus never attacked him (not that I can remember atleast). I also think that him leading the Nexus could not only lead into Miz/Bryan and Miz/Cena feuds but it could also create a potential Barrett/Miz "power struggle" which may lead to Nexus breaking up, but not necessarily getting owned out of the WWE.
