It is mainly for deep-linking from urls in other apps/sites. Primarily so apps can reenter previous states rather than opening on the app, in some cases to push data to the app.
Example: Game app has buttons on a website to play specific levels with some special powerup, so you can link to it just like a website but in the app play the level and bypass the main screen etc.
It is a bit like DNS hosts within the devices but the only problem is it is not standard and there is no listing so it is more like old school file type or port claiming, there may be clashes/name collisions.
