"all" and "missed" in notification centre

[outlawarth]

Pardon my ignorance but what is the difference between "all" and "missed" in notification centre? Aren't all alerts in notification centre missed anyways? Why distinguish between the two?

From what I can tell, "missed" is all the notifications you get when you're device is locked. If you get a notification while you're using your device and decide to ignore the banner, it won't go into the "missed" section.
