For the first time, we report that the radial alignment signal of nucleated dwarfs is stronger than that of non-nucleated ones at 2.4$\\sigma$ confidence level, and the dwarfs located in the outer region ($R>R_{\\rm{vir}}/3$; $R_{\\rm{vir}}$ is the Fornax virial radius) show slightly stronger radial alignment signal than those in the inner region ($R
