Correct by all means. It is important to note, to avoid misunderstandings, that GS mini is primarily designed to deal with headwinds in order to maintain, as the name suggests, a minimum Ground Speed during the final approach.
The great advantage is to have the IAS increasing with headwind increase, hence if the headwind components drops or shifts to a tailwind the aircraft will not be in a low energy state with IAS dropping and low thrust.
In case of an approach with wind calm or 0/0, an increase in tailwind will be dealt in the same way on an Airbus FBW with managed speed as any other type, i.e. there will be the need to increase thrust to maintain the computed Vapp (Vls+5).
