MechEngr - the stabilizer cutoff switches are within a foot of the Captain's right hip/thigh. Possible as close as 6 inches. (12-25 cm).
I have about 4,500 hrs of listening to the trim wheel on Boeing aircraft. I have another 14,500+ hrs on Boeing jets without a trim wheel but the red guarded cutoff switches are still right next to the Captain's hip on those aircraft. In all of them utilizing the stab trim cutout switches is a known procedure for uncommanded or runaway stabilizer trim movement.
It's stunning to think a pilot wouldn't flip the red guarded cutoff switches next to their hip if the trim ran uncommanded for 9.2 secs. A fraction of pilots might let that happen. But then it starts a second time and runs ND for another 9.2 seconds and you feel the plane getting farther and farther out of trim? That's scary to even contemplate. If that happened to any of us it would be one of our top career aviation stories if it happened once. We know it's dangerous on any large jet. If we were telling the story and continued with "and then the trim started to run ND again!!!" would have every pilot listening on the edge of their seats.
Interestingly the 777 and 787 QRH say to not exceed, or perhaps maintain, the current speed. The 737/757/767 make no mention of maintaining your current speed or not exceeding a certain speed.
