Correct, this is not referring to multiple sessions, but a given execution could 
have multiple operations that are each using up to work_mem simultaneously.

That is addressed in the last revision of the patch.

-        Note that for a complex query, several sort or hash operations might be
-        running in parallel; each operation will generally be allowed
+        Note that a complex query may include several sort and hash operations,
