In arXiv:2109.00065, it was pointed out that superstring theory on $AdS_3$ with $(NS,NS)$ $B$-field background and $R_{AdS}/l_s=\sqrt k1$, and show that the resulting picture matches that discussed in the bosonic case in arXiv:2110.07535. We argue that in the critical case, $k=1$ hep-th/0503121, the $\mathbb{Z}_2$ twisted deformation remains non-trivial. This resolves some confusions in the literature.
