Abstract: We show that there exist suitable sequences $\{w^{(k)}\}_{k \ge 0}$ and $\{w'^{(k)}\}_{k \ge 0}$ of Weyl group elements for a given perfect crystal of level $l\ge 1$ such that the path realizations of the Demazure crystals $B_{w^{(k)}}(l\Lambda_0)$ and $B_{w'^{(k)}}(l\Lambda_2)$ for the quantum affine algebra $U_q(G_2^{(1)})$ have tensor-product-like structures with mixing index $\kappa =1$ .
