During the evacuation of the ANA 787 there were probably not enough passengers to warrant opening door 4L as everyone that went back to evacuate used door 4R.
In theory if you have a F/A at each door (I believe that all 8 doors are "manned"), then I suppose that all doors/chutes should have been activated by their local F/A, regardless of pax flows forward/back. Since the slide is not deployed and the door is still shut it does not appear to be a malfunction, hence my question about whether they run reduced F/A numbers on domestic flights (i.e. only one at the back), given the light load factor on the flight at that time of day.
As mentioned, the evacuation was timely (and very orderly), so no problems there...
