It’s basically the app going “Hey, default web browser, I need your help. See, this dude wants to look at a webpage but I’m too lazy to learn how to open web pages myself. Can you come over and pretend to be a part of me for a quick second?”
The difference between just embedding a WebView is that, with this approach, any modifications to the browser also apply. So, if you have, say, uBlock installed on your Android Firefox (as you should), it will work in those pages too.
