     This command can be used to restore stacks of changesets to an obsolete
     state, creating identical identical copies.
 
+    When we rewind to an obsolete version, we also rewind to all its obsolete
+    ancestors. To only rewind to the explicitly selection changesets use the
+    `--exact` flag. Using the `--exact` flag can restore some changesets as
+    orphan.
+
     The latest successors the obsolete changesets will be superseed by these
     new copies. This behavior can be disabled using `--as-divergence`, the
     current latest successors won't be affected and content-divergence will
