As others have said, in effect nothing has changed apart relinquishing the title of chairman.. if anything, he's now possibly in a better position to pass extra payments to players. He's still the owner and has said he will continue to offer financial support.
If Sarries think its is going to appease the other 12 clubs then I suspect they'll be mistaken.
Things will only change when he sells his shares but who is going to be able pay what he is possibly now owed (£40m possibly) having bought Remgro out.
