Yes, you did miss something. To be honest, I too have missed that same thing.

I think all the check lists that say something about manually trimming with the wheel and/or hold/grasp the wheels will need to be rewritten.
And then, what will the new procedure for trimming with cut out switches set to cut out be? How to stop trim runaway when wheels supposedly cant be stopped by grabbing them?
I think there hides a lot of problems for Boeing in the manual trim wheel system.
