 Pick $b_j \in A \otimes_{A_0} B_0$ mapping to $1 \otimes x_j$ in
 $A \otimes_{A_0} C_0$. For some $i \geq 0$ we can find
 $b_{j, i} \in A_i \otimes_{A_0} B_0$ mapping to $b_j$.
+After increasing $i$ we may assume that $b_{j, i}$ maps
+to $1 \otimes x_j$ in $A_i \otimes_{A_0} C_0$ for all $j = 1, \ldots, m$.
 Then this $i$ works.
