 When \lstinline!y! passes through zero, neither form of the equation would have a solution in an open neighborhood of \lstinline!y! $= 0$, and hence solving the equation would have to fail at some point sufficiently close to \lstinline!y! $= 0$.
 Without event generation, on the other hand, the equation can be solved easily for \lstinline!x!, also as \lstlinline!y! passes through zero.
 
-In inverted form this equation is \lstinline!x=sign(y)*sqrt(abs(y))!, with similar issues.
+In inverted form this equation is \lstinline!x = sign(y) * sqrt(abs(y))!.
+With event generation, the call to \lstinline!sqrt! would fail when applied to a negative number during root finding of the zero crossing for \lstinline!abs(y)!, compare \cref{events-and-synchronization}.
+Without event generation, on the other hand, evaluating \lstinline!sqrt(abs(y))! will never fail.
