There is no suggestion in the report that the PF was not monitoring the approach with hands on the yoke.
Entirely agreed. Also worth noting (from section 1 of the report):
Some 34 seconds before touchdown, at 430 ft agl, the commander announced that the approach was stable, to which the co-pilot responded “just”. Seven seconds later, the co-pilot noticed that the airspeed was reducing below the expected approach speed of 135 kt.
The comment I've put in italics appears (to me) to confirm that PF was indeed still following the glideslope well below 600ft, whether (as you say) assisted by autopilot or not. He knows there's a thrust problem and that PNF is troubleshooting.
According to the report it's not until about 7secs later (300ft ?) that speed drops below Vref, and even then PF is probably still thinking/hoping thrust will kick in any second now...
