There's the handler in busybox-1.24.1/init/init.c:

  788 /* The SIGPWR/SIGUSR[12]/SIGTERM handler */
  789 static void halt_reboot_pwoff(int sig) NORETURN;
  790 static void halt_reboot_pwoff(int sig)
  791 {
  ...
  803         run_shutdown_and_kill_processes();
  ...
  817 }

I think it was intended to halt the system.

Thanks
