Abstract
In the study by Birdi <i>et al.</i> molecular dynamics simulations were employed to investigate the coarsening dynamics of bent-core liquid crystals with a focus on the phase transition from a polar smectic X phase to the chiral twist-bend phase. A key finding is the emergence of an intermediate splay-bend phase before the system reaches the stable twist-bend phase. In this comment, we rectify the erroneous assumption that led to the improper conclusions and elucidate that the intermediate system studied by Birdi <i>et al.</i> is either a disordered smectic X (banana phase B1) or splay-bend smectic.
