The oscillation behavior described by Tang [Phys. Plasmas 19, 073519 (2012)] differs too greatly from previous experimental and numerical studies to claim observation of the same phenomenon. Most significantly, the rotation velocity by Tang [Phys. Plasmas 19, 073519 (2012)] is three orders of magnitude larger than that of typical "rotating spoke" phenomena. Several physical and numerical considerations are presented to more accurately understand the numerical results of Tang [Phys. Plasmas 19, 073519 (2012)] in light of previous studies.
