we have the same report
the difference is that you seem to believe that the first crew action was commanding nose down while i seem to follow the report thinking that 'the autothrottle and the flight crew commanded full thrust' and this has happened much earlier - just after the speed got below 135kt or latest
And to me it is fully understandable as adding more thrust is what most pilots do to add speed while landing
. And since B777 is a jet hence it took a while to acknowledge no speed increase. And all this is the time AP was constantly increasing pitch.
I would not consider take this time as no action.
