 \subsection{Coherence and Patch Inclusion}
 
 Consider some $D \in \p$.
-$B \not\in \py$ so $D \neq B$.  So $D \isin B \equiv D \isin L$.
+$B \not\in \py$ so $D \neq B$.  So $D \isin B \equiv D \isin L$
+and $D \le B \equiv D \le L$.
 
 Thus $L \haspatch \p \implies B \haspatch P$
 and $L \nothaspatch \p \implies B \nothaspatch P$.
