I think Centaurus has misunderstood the SOPs. As JW411 has indicated, P2 flew the entire approach, with the firm intention of going around at DH, unless P1 said "Land" in response to P3's call "Decide".
There was no transfer of control during a missed approach.
If P1 called "Land" at DH, P2 would simply let go of the controls and be prepared to select reverse and lift-dumpers. If P1 said "Go-around", or said nothing - P2 would go-around.
