The "column cutout switch" is what is inhibited when MCAS is operating. The trim switches (both of them) are not inhibited by MCAS. In this incident, either the captain or first officer could have continued to toggle for nose up trim. After a few seconds (10?), MCAS would again try to trim down, and it could be countermanded by either crew position. Indefinitely. Sure, it is irksome, but it can be stopped anytime with the electric trim cutoff switches (not the same thing as the column cutout switch) just like the runaway trim checklist says.Then what is meant by the word "inhibit" (in the MCAS description).
No doubt MCAS will be made better. But I don't fault Boeing engineers for failure to anticipate that there would be two crew members on the flight deck who would both choose to stop trimming the airplane with the electric trim AND elect to not disable the electric trim.
