sshd_config#PermitRootLogin typo

[lu hu]

Hello,

http://man.openbsd.org/sshd_config#PermitRootLogin
says
...The default is prohibit-password.
If this option is set to prohibit-password (or its deprecated alias, 
without-password), password and keyboard-interactive authentication are 
disabled for root.

SO:

if I remove the PermitRootLogin line from sshd_config, then rcctl restart sshd, 
then why can I see

66# sshd -T|grep -i permitr
permitrootlogin yes
66#

instead of prohibit-password ?

Thanks!
