Well, it doesn't actually say that - as given: "Even if the aeroplane does not begin to shudder or otherwise indicate an imminent stall, it may not be turning quite as quickly as it would if the stick is very slightly eased forward."

As has been said before - the buffet region of flight has 'depth' due to washout and the progressive nature of the stall across the wingspan. It's possible for a pilot experienced on type to know how much he can pull through the buffet before a full-blown stall & consequent stall and/or flick will occur.

The 'buzz' or 'nibble' does not necessarily presage an imminent stall, it just indicates that the inner part of the wing has exceeded max AoA, the airflow has separated from that surface and is impinging on the elevator.

That's sort of true, but not completely. For a wing with washout, max turn performance might not occur until some portion of the inner part of the wing is stalled and the wing as a whole has reached CLmax.
