We study a saturation process of the centrifugally driven curvature drift instability (CDI) in the magnetospheres of active galactic nuclei (AGN) close to the light cylinder surface (LCS) to examine the twisting of magnetic field lines leading to the free motion of AGN winds, that completely kills the instability. We generalize our previous work by considering relativistic electrons with different phases. Considering the Euler, continuity, and induction equations, by taking into account the resonant conditions, we derive the growth rate of the CDI. It is found that the net effect of phase differences leads to exactly the same result as for the case of zero phases. We show that due to the centrifugal effects, the rotational energy is efficiently pumped directly into the drift modes, that leads to the generation of a toroidal component of the magnetic field. As a result, the magnetic field lines transform into such a configuration when particles do not experience any forces and since the instability is centrifugally driven, at this stage the CDI is suspended.
