The aircraft was stable but aproach power does not have to be absolutely set until 500'. It may be that spped was reducing to vref +5 (or whatever they were using) at 600'. However it is clear that at this point or at 500' things would have been normal. From there on the aircraft would have continued to lose speed. The A/T would then have demanded more power which it would appear never arrived for one reason or another.
Both auto and of course manual thrust is available. Neither gave the power required to maintain the speed. Then you have to sacrifice something, speed or height.
Their actions ensured that no-one was killed.
