villas,
In direct law you directly move elevators gives better control.
Agreed.
But using the same logic, why is there not a similar procedure with B & Y SYS LO
PR? (R ELEV INOP).
The big differences are no Slats - hence there is a big trim change when Flaps 2 selected. Consequently manual thrust is recommended so that the thrust change couple can be controlled better; and there are no ailerons for roll control with only Y Hyds available,

Is it acceptable to disconnect the A/THR upon completing the landing configuration ?
Well, the QRH says A/THR off early during the procedure, even before reducing speed to below 200 kts. The sim ATHR might be able to cope OK, but it sounds like Airbus want to give the responsibility to the pilots.
Similarly, QRH Flaps/Slat jammed: "A/THR recommended except in the case of a G & B Lo
PR warning"
