Here is some info I dug up from various resources, on properly retraining your TPMS Sensors.
Part of this was inspired by the fact that I was forced to purchase new TPMS sensors for my after market TSW wheels.
My Manager pal (Nick Madsen) who works @ NTB (in Downers Grove, IL) was not able to retrain the new sensors as the tool they had was not compatible with Ford.
So off to the Dealership I went.
The tech performing the resets was a newer kid, who also had difficulty getting the car into true "on" mode.
Once I showed him how to do that part of it (see/refer to video below), I remained in the Service area (near the car while chit chat'n w/ another employee) and the tech followed the same procedure(s) as outlined in my OP on this topic.
Worked like a charm.
It's important to note that FMC did switch over mid 2010 from the "banded" style (like I have) to the much easier "valve" style sensors.
Here's that video I was referring to.....
