Let $g$ be a connected, semisimple and simply connected algebraic group defined and split over the finite field of order $p$, and let $g(n)$ be the corresponding finite chevalley group and $g_n$ the $n$-th frobenius kernel. Pillen has proved that for a $3(h-1)$-deep and $p^n$-restricted weight $\lambda$, the $G$-module $Q_n(\lambda)$ which is extended from the $G_n$-PIM for $\lambda$ has the same socle series as the corresponding $kG(n)$-PIM $U_n(\lambda)$. Here we remark that this fact already holds for $\lambda$ being $2(h-1)$-deep.
