Does the Exit Course trigger do anything else?

I know the "Exit Course" trigger is supposed to close the browser window -- for example when the user clicks a button. But does Exit Course do anything else besides that?

I'm asking because I have a very similar issue as this older discussion: Exit Course trigger on SL3/HTML5

The solution described in that discussion is basically what we're trying to do:  using JavaScript to close the window when the exit button is clicked, instead of using SL360's Exit Course trigger. That's because we publish the course as HTML and store it in the cloud, and our website accesses it through an iframe. (We're not using an LMS.)

So, if I don't use the Exit Course trigger, is there anything the story will skip doing that it should do?
