[Dovecot] Is this odd?

[LuKreme]

 $ doveadm user kremels
field   value
uid     1033
gid     1033
home    /home/kremels
mail    maildir:~/Maildir
system_groups_user      kreme

 $ doveadm user user at virtual.example.com
field   value
uid     89
gid     89
home    /usr/local/virtual/user at virtual.example.com/
mail    /usr/local/virtual/user at virtual.example.com
mail_location   /usr/local/virtual/user at virtual.example.com

The local users doesn't have a mail_location set at all, and has a very different mail definition. This seem to be a side-effect of the fact that the home of the virtual user is the top level maildir, but should I set mail to maildir:~ ??
