The person decided to do it via shell hacks as it was quite common to do it that way back then. It's a good thing to get rid of such hacks and patch the features into daemon itself anyways, indepedent of whether or not systemd is used for booting.
As far as I can say from the proposed config, the features are actually implemented in atd and the "hacks" just translate sysconfig variables to command line parameters. Many init scripts do things like this as daemons rarely parse /etc/sysconfig themselves.
