In the present work, we re-analyze the available data for $\gamma p\toK^{\ast +}\Sigma^0$ and $\gamma p \to K^{\ast 0}\Sigma^+$ by considering thecontributions from the $N(2080){3/2}^-$ and $N(2270)3/2^-$ molecules instead ofany nucleon resonances in the $s$ channel, where the $N(2080)3/2^-$ wasproposed to be a $K^\ast \Sigma$ molecule as the strange partner of the$P_c^+(4457)$ hadronic molecular state, and the $N(2270)3/2^-$ was assumed tobe a $K^*\Sigma^*$ molecule as the strange partner of the $\bar{D}^\ast\Sigma^\ast_c$ bound states that are predicated as members in the sameheavy-quark spin symmetry multiplet as the $P_c$ states. It turns out that allthe available cross-section data can be well reproduced, indicating that themolecular structures of the possible $N(2080){3/2}^-$ and $N(2270)3/2^-$ statesare compatible with the available data for $K^\ast\Sigma$ photoproductionreactions. Further analysis shows that for both $\gamma p\to K^{\ast+}\Sigma^0$ and $\gamma p \to K^{\ast 0}\Sigma^+$ reactions, the$N(2080){3/2}^-$ exchange provides dominant contributions to the cross-sectionsin the near-threshold energy region, and significant contributions from the$N(2270)3/2^-$ exchange to the cross-sections in the higher energy region arealso found. Predictions of the beam asymmetry $\Sigma$, target asymmetry $T$,and recoil baryon asymmetry $P$ are presented and compared with those from ourprevious work. Measurements of the data on these observables are called on tofurther constrain the reaction mechanisms of $K^\ast\Sigma$ photoproductionreactions and to verify the molecular scenario of the $N(2080){3/2}^-$ and$N(2270)3/2^-$ states.
