pg_upgrade, can you use the rsync method of upgrading a standby if you used clone mode?

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/17/pgupgrade.html
Description:

In the documentation for pgupgrade
(https://www.postgresql.org/docs/17/pgupgrade.html), step 13 gives
instructions for quickly upgrading standby servers with rsync, and says that
it only works if you used link mode.  However, step 12 gives the impression
that clone mode is very similar to link mode.  I think the documentation for
step 13 would be improved by explicitly stating whether clone mode is
compatible with the rsync method or not.

Thanks!
