We agree that there is no contradiction between Wang and Hahm [Phys. Plasmas 17, 082304 (2010)] and Sosenko et al. [Phys. Scr. 64, 264 (2001)]. However, by explicitly evaluating the change in phase-volume due to the electrostatic potential [T. S. Hahm, Phys. Plasmas 3, 4658 (1996)], Wang and Hahm [Phys. Plasmas 17, 082304 (2010)] has demonstrated that the polarization density remains the same even when the polarization drift explicitly appears in the gyrocenter equations of motion, and has derived an energy invariant in general toroidal geometry.
