After AIMS-2 BP V17B it is the case.
If the pitch mode is FLCH SPD, VNAV SPD, or VNAV PTH and A/T is in HOLD or THR mode, and speed decreases into the amber band, the A/T will change from HOLD to THR mode if necessary, and thrust will increase proportional to the amount speed has decreased into the amber band.
