Apple's documentation indicates that notifications are in some cases triggered by the fact that a device has followed you to your home or other "significant location". [1]
It goes the other way around. Enabling significant locations allows your device to queue up notifications like that to basically be "you have arrived" updates, versus while you are driving or otherwise engaged having a sudden notification go off, which some people find alarming. It doesn't require significant locations, but that's when it might decide to wait to tell you.
