 --root::
        Rebase all commits reachable from <branch>, instead of
        limiting them with an <upstream>.  This allows you to rebase
-       the root commit(s) on a branch.  Must be used with --onto, and
+       the root commit(s) on a branch.  When used with --onto, it
        will skip changes already contained in <newbase> (instead of
-       <upstream>).  When used together with --preserve-merges, 'all'
-       root commits will be rewritten to have <newbase> as parent
+       <upstream>) whereas without --onto it will operate on every change.
+       When used together with both --onto and --preserve-merges,
+       'all' root commits will be rewritten to have <newbase> as parent
        instead.
