That’s because the definition of Vls in this case changes from 1.23Vs1g to 1.13 Vs1g.
I don't think so.
From FCOM DSC-22_10-50-20 Definition of VLS,
"VLS:Lowest Selectable Speed.
Represented by the top of an amber strip along the airspeed scale on the PFD.
Computed by the FAC, based on FMS, and corresponds to 1.13 VS during takeoff, or following a touch and go
Becomes 1.23 VS, after retraction of one step of flaps.
Becomes 1.28 VS, when in clean configuration."
Doesn't mention a GA. Apparently - you need wheels on the ground to trigger 1.13 VS1g logic.
