The reboot is done by the ExecStopPost handler of the service:

$ cat /nix/store/vc8pxy21iynvqkgy6r8f2q46yfxlqr1m-freertr-exec-stop-post
#!/nix/store/a3fc4zqaiak11jks9zd579mz5v0li8bg-bash-4.4-p23/bin/bash
if [ $EXIT_STATUS -eq 4 ]; then
  echo "cold reload requested by freeRtr, initiating reboot"
  /nix/store/q6ylicsava582g55mdx0788yg2fib7js-systemd-246.6/bin/systemctl 
reboot
fi
exit 0

I have also set

Restart=on-failure

The difference to your method is that the service doesn't restart if
it exits with status 0.  I guess we need to decide whether the user
should be able to stop the service from the CLI without an automatic
restart or reboot.
