relearn procedure:
TCM Adaptation
It is necessary to perform a drive cycle to provide the proper baseline transmission adaptation. The adaptation procedure should be performed if any of the following procedures are performed:
•
Transmission Assembly Replacement
•
Transmission Control Module Assembly (TCMA) Replacement
•
Internal Transmission repairs
•
Torque Converter Replacement
1. With the scan tool, clear any DTCs that may be set.
2. Drive the vehicle until the vehicle temperature is greater than 30˚C (86˚F).
3. After the vehicle has reached normal operating temperature, and with the scan tool, monitor actual gear state. Drive the vehicle normally with the accelerator pedal between 10% and 20% until 7th gear has been achieved, approximately 76 km/h (47 mph). After 7th gear has been achieved, coast down to 30 mph with no application of the brake or accelerator to allow a 6-5 shift. Brake the vehicle to a stop. Repeat this procedure 5 times.

Maybe there are 2 resets. One for "driver habit" adaptation and one for wear adaptation. I reset mine again a couple days ago via the BMWAI tool...it actually says "driver habits memory" (look at post #23). No big deal...felt a little bit better to me after, but this is just my judgement.
Possibly the re-learn procedure you described is for the wear adaptation reset. ? And the wear adaptation reset is not accessible via noobs like me?
