CONF iture;
The first time we have heard about that procedure was in 2004, I believe.
It was the subject of a FCOM BULLETIN called AIRCRAFT HANDLING IN FINAL APPROACH
The interesting part is, that procedure has proved to have more drawbacks than advantages, so, as discretely as it could be I must say, Airbus has decided in 2009 to not recommend to use this procedure any longer.
If the A/THR performance is not satisfactory, the flight crew should take over and control the thrust manually.
Yes, I recall the Bulletin.
My comment re manuals was in reference to present-day publications, a number of which I surveyed and reported on and included an acknowledgement that the procedure has it's problems as per Chris' comments. Some of them referenced the procedure, some didn't, so likely your last statement from the FCOM is the preferred response.
