There's no way the rest of the team expected the lead to roll out of the left turn when he did. It also looks as though the leader's roll-rate as he rolled out of the left turn was higher than the rate he used during entry. Possible therefore the lead made a rather late decision to roll-out, and I doubt very much he had called it. A rate of change of bank that the lead used rolling right to wings level would have to be called in anything other than a basic 3-ship for the guys on the wing to have a chance of keeping on the references. So much of the close formation manoeuvring relies upon the 'procedural' control inputs applied based on the leaders voice/tone and of course the expected manoeuvre.
