What's the difference between call_action_list and run_action_list?

I have been trying to figure this out for a while, but it's still too vague for me to tell which one to use.

The APL will go back to the place call_action_list was used if it doesn't find an usable action in the sub-APL. run_action_list doesn't do that.
