Those bug fixes get back-ported, and the bugs fixed may have been introduced in versions of systemd released after whatever got included in RHEL/Debian. Speaking as someone constantly frustrated at the glacial pace at which RHEL and Debian-stable update themselves (which is admittedly a feature), it's nice to see them adopting somewhat modern stuff when they make major releases (if systemd v208+backports could be considered modern).
