Yes, on that previous flight, you can see the fight between manual electric and automatic trim inputs. In one 50-second stretch, the aircraft goes from 4400 to 5600 feet, back down to 4400, and up to 5600. Someone want to imagine what that would feel like?
It looks like they used the manual electric trim to fight the MCAS for another 45-50 seconds, and then hit the cut-out. You can see the MCAS makes one last nose-down command that doesn't translate into trim movement. 150 seconds later, as they're considerably higher, they try again, disabling the cutout and immediately ordering nose-up trim. MCAS gave them a whole bunch of nose-down, so they cutout again and manually cranked the desired trim.
