That chronological requirement is only for the SOB chain itself.

To quote Documentation/process/submitting-patches.rst:

Standard sign-off procedure applies, i.e. the ordering of Signed-off-by: tags should
reflect the chronological history of the patch insofar as possible,

which is exactly what I wrote above:

^^^^^^^^^^^^^^^^^^^^^

In fact it would be crazy to require that all the tags are chronological,
in the random order they arrived, which the commits I pointed out appeared to be.

Thanks,
