You are quoting from the v10+ documentation but using 9.6
You also need to read about archiving[1] since when it is enabled the
rules for WAL retention are modified to meet the needs of archiving,
specifically WAL cannot be removed from the host system until the
host's archiving system knows that the same file exists in the
archive.
