Not sure you are right about the FMGC correcting altitudes/FL's...
As I understand it, unless you have the QFE option, it flies the a/c to make the BARO altimeter read what is in the FCU window - the BARO REF setting is irrelevant. Hence the warning not to change the BARO REF when in ALT*, because that changes the target altitude.
In descent, the displayed targets on MCDU above Trans Alt do change from FL to altitude with BARO REF being STD or QNH.....
