A logic that expects and requires flight crew to retard the thrust levers before touchdown as per SOPs.
The point is that the MLG compression is latched for 3 seconds, and ground spoilers come when thrust levers are retarded to idle.
Since there have been other incidents during which flight crew have not retarded thrust levers before or at touchdown, but while in the air upon a bounce, the logic has been changed.
This entire sequence seems to me, on the face of it, what one would expect. The logic of the automation behavior is predicated on specific crew behavior; this specific crew behavior has not always occurred; the automation behavior has been modified to adapt to these rare instances in which crew do not follow SOPs.
