To say it differently : 
 "/usr/lib/systemd/system/“ is the default configuration at the distribution level, and /etc/systemd/system/ is the configuration for your system.
Thus configuration in /etc/systemd/system/ prevails over "/usr/lib/systemd/system/“.

This setup (/usr/lib/systemd and /etc/systemd/) allow us to have useful command line like systemd-delta 

Snippet of systemd-delta man page :
systemd-delta may be used to identify and compare configuration files that override other configuration files. Files in /etc have highest priority, files in
       /run have the second highest priority, ..., files in /lib have lowest priority.

Regards,

PS : It is easier to use “# systemctl get-default” than  “# ls -l".
