They don't have the same instance state. You can use "adb shell dumpsys activity" to see the system's activity stack; each of those entries is an "instance" of an activity as far as the system is concerned.
Killing a process while its UI is in the background is a normal situation on the system -- it is what happens when memory is low. It is expected, and doesn't impact the instance that the system has on the stack. (It will just have to ask the app to re-create it the next time the user visits it.) Killing a process while it is in the foreground is not normal. In that case the system didn't have time to ask it to save its instance state, so it can not re-start the activity in its last state, so it throws that instance away.
