@@ -311,10 +311,11 @@ A sequence is an expression of the following form:
 \begin{quote}
 {\tacexpr}$_1$ {\tt ;} {\tacexpr}$_2$
 \end{quote}
-The expressions {\tacexpr}$_1$ and {\tacexpr}$_2$ are evaluated
-to $v_1$ and $v_2$ which have to be tactic values. The tactic $v_1$ is
-then applied and $v_2$ is applied to the goals generated by the
-application of $v_1$. Sequence is left-associative.
+The expression {\tacexpr}$_1$ is evaluated to $v_1$, which must be
+a tactic value. The tactic $v_1$ is applied to the current goal,
+possibly producing more goals. Then {\tacexpr}$_2$ is evaluated to
+produce $v_2$, which must be a tactic value. The tactic $v_2$ is applied to
+all the goals produced by the prior application. Sequence is associative.
