Hi -1000,
In fact during an RTO both pilots monitor aircraft deceleration. Selecting the flaps to, let's say, 40 (737) is an action done by the CM2 below 60 kts, so at a relative low speed. I would not say that by doing this flap selection you combine RTO and pax evacuation since once the aircraft is nearly stopped you have to decide if it is the case to stop on the runway and apply the hopefully correct NNC or vacate the runway. If both procedures were combined you would stop on the runway, set parking brake, speed brake down even for something not so relevant (let's say you do a low energy RTO). I would say that RTO and pax evacuation start to get more combined for high energy RTO's since you stop for major malfunctions that can lead to a pax evacuation. Anyway as you always have to analyze the situation once the aircraft is under control, the pax evacuation NNC is obviously something you end up with after all the rest is done.
That's my point of view
