I am perfectly aware of this fact, yet I am still used to close them for convenience (always starting from homescreen, after launching an app I'm always at the start screen and not for ex. in a conversation I'm not interested in at the moment - and when I need to multitask, I have 2-3 apps that I need in task switcher instead of 10). And right edge is easier accessible then the back button in top left corner - especially on pretty big Pro 5 ;)
Of course that it's not a killer feature, but a little neat thing which is probably quick and pretty easy to implement.
