We perform time-dependent calculations of triply-differential cross-sections (TDCS) of two-photon double electron ionization of the aligned \"molecule. Our TDCS results for equal energy sharing between photoelectrons agree quite well with a recent time-dependent calculation by Guan et al. [Phys. Rev. A 77, 043421 (2008)] who employed a slightly different numerical technique. We supplement these studies by calculating TDCS at an unequal energy sharing and by generating symmetrized ionization amplitudes.
