The second link states

  SoB chains should reflect the **real** route a patch took as it was
  propagated to the maintainers and ultimately to Linus, with the first
  SoB entry signalling primary authorship of a single author.

This series will (eventually) be upstreamed by me through a pull request
to Mauro. Paul's SoB will thus not be needed. Of course you have no way
to know this when reviewing the series on the list.

Adding a SoB line when taking a patch in a git tree is standard
practice, but when posting unmodified patches to a mailing list, there's
more of a grey area. Look at
https://lore.kernel.org/all/20221024113058.096628238@linuxfoundation.org/
for instance, posted by Greg, but without his SoB.
