It's conditionalized via ConditionNeedsUpdate=, which means it is only run when /etc is older than /usr. (This is tested via checking modification times of /etc/.updated and /usr), see explanation on systemd.unit(5). The usecase for this is to permit systems where a single /usr tree is shared among multiple systems, and might be updated at any time, and the changes need to be propagated to /etc on each individual systems. The keyword is "stateless systems". Note that normally this should not be triggered at all, since this only works on systems where /usr itsel is explicitly touched after each updated so that the mtime is updated. That should normally not happen, except when your distro is prepared for that, and does that explicitly. Hence, in your case, any idea how it happens that your /usr got its mtime updated?
