In the comment to my recent work (Erofeev 2023 Plasma Phys. Control. Fusion65 085014) Chao Dong and Ding Li have pointed out a mistake that I missed in the last stage of my research (Dong and Li 2024 Plasma Phys. Control. Fusion66 068001). I will consider its essence and impact on the basic results reported in the paper in a slightly different way.
