Well, the shots of the model perfectly allow for four large doors, one for each between-piers, even if the model didn't have that many doors inside or outside...
If Okudagram numbers are supposed to make any sense at all, my interpretation of the numbers adjoining the four doors here would be queue numbers. Departure 15 is scheduled for the "East" gate next, while Departure 7 is going to leave through "West". And Departure 15 happens to be the flight with Flight Plan 9780 for the day, as expanded on that screen. Departure 11 has Plan 7858.
That's the sort of information I'd want on my screen if I were guiding these ladies in and out. Door numbers would be irrelevant: I'd know them like the back of my hand already anyway.
