That could very well be. BUT.....you still have an engine left for some thrust. BA038 had NOTHING.
Yes, of course... But the aerodynamic principles are the same. The concern is to get rid of the parasite drag. On a heavy jet with the landing gear down and full landing flaps and no thrust you decent like a stone at VREF Or you bleed off your speed down to the speed shaker in no time if you maintain a 3 deg G/S, like the crew of the TA B738 in Amsterdam experienced with their throttles closed at idle.

The difference in stall speed and hence available lift is not much at the later stages of the flap settings - but the difference in drag is enormous. Which is handy to have, if you got your engines running. It will require a rather high power setting, which gives you a much faster throttle response.

So IMHO even if they couldn't maintain the speed and raised the AoA to get more lift and therefor increased induced drag, they drag was still less then the parasite drag you have with full flaps. I think the report also mentioned, that if they had maintained the configuration, they would have touched down a bit earlier. Which seems to support my thoughts above.
