If as Commander (but PNF) I say "STOP STOP STOP" during the takeoff roll, I expect the PF to stop the thing, not to simply say "you have control".
As a Commander, I have no intention of waiting for the F/O to do anything when I shout out that we're stopping.
The Captain has the thrust levers and feet on the brakes, and both those get actioned
very quickly regardless of the F/O making any other calls.
Other companies may have the F/O actioning the stop, but I don't know of any.
