And yes, you are right, if ABSU is in AUTOLANDING state (and this mean ГЛИССАДА must be activated), then full throttle makes same effect as pressing any of three УХОД buttons.
The only thing I can consider, that possibly ANY signal from steering column are recorded by FDR.
There was no autolanding mode selected. Therefore no autoland, no automatic goaround, no full autothrottle, and no recording of pushing the button (even if they did) in the FDR.
Thatīs how i understand the report.
