I wouldn't even be surprised if the FO was PIC on landing and the captain didn't have time to take over control of the a/c....
Captain wouldn't have necessarily taken the controls anyway. If my understanding is correct (I'm found flying at the other end of BAs jets) in an emergency situation the guy/girl in the right hand seat handles the flying and the captain manages the situation. In normal conditions the captain and F/O complete equal numbers of landings, the only exception is in a strong crosswind or autoland when the captain is always handling.
