The branching ratios (Br) of lepton flavor violating decay of the standard-model-like Higgs bosson (LFVHD) $h\rightarrow\mu\tau$, predicted by the minimal (MSS) and inverse (ISS) seesaw models, are compared to explain why these models predict very different values of Brs. We will show that these Brs enhance with large and increasing heavy new neutrino mass scale $m_{n_6}$. The ratio between two branching ratios predicted by the ISS and MSS can be estimate by a simple factor $m_{n_6}^2\mu_X^{-2}$ , where $\mu_X$ is the small neutrino mass term appearing in the ISS only.
