I have re-read your excellent post but still fail to get an answer to a question I posted a few hundred messages ago: what would have happened (regarding the spoilers and auto braking) if the crew had retarded the 2nd T/L after touchdown. Would that be sufficient to disambiguate the logic or do you have only "one shot" for the automation to do it's magic ?
atakacs,
Sorry, the answer is exactly as bsieker has stated. At any time if the second thrust lever had been retarded enough to be considered "near idle" (15 degrees or less TLA below 10 feet) the logic for ground spoiler extension would have been made. Autobrakes would then have engaged assuming that manual braking had not already disarmed them.
