The reset button is only on one slide, it resets a bunch of variables to their original value, sends the user to the previous slide which is just a filler slide that goes back to the original slide.
The shared action is set up on an information button, it's set so that it hides a group of smart object buttons (the same group that it then opens one object in that group) and then shows one smart object button.
Clicking the smart object button closes the object and might do other stuff, I'm not sure but it uses an advanced action (not shared).
