The answer is on the next page in your FCTM. It is all about the initial spool-up of the engines to 40%N1. In short:
Rolling:
No use of brakes to achieve 40%N1, when aligned and on centerline, release nose wheel steering, and set takeoff thrust. This can be done either during the alignment from the taxiway (has nothing to do with high-speed exit taxiways by the way, the goal is not to accelerate on the taxiway, Boeing is clear it is to be done with "normal taxi speeds"), or also when already positioned on the runway.
Standing:
Use of brakes to achieve 40%N1, when engines are stable ensure the nose wheel steering is released, then release brakes and promptly set takeoff thrust.
