Hi,
unfortunately %h is not really supported anymore. Man page should be
updated, since it's rather misleading at the moment. It was removed
in systemd 209:

  * %h, %s, %U specifier support is not available anymore when
    used in unit files for PID 1. This is because NSS calls are
    not safe from PID 1. They stay available for --user
    instances of systemd, and as special case for the root user.
