The white circle appears when the opponent presses the parry button and it doesn't block any melee attacks during its active frames. It then starts disappearing over the course of 4 seconds, indicating to you as a player that their parry is on cooldown.
If however, the opponent makes the parry successful (in other words blocks a melee attack) the white circle and disappearing for 4 seconds is still happening (again indicating to you that their parry is on cooldown) although that information is incorrect since opponent has parry already available.
