When an SOS is initiated, and is cancelled before the countdown finishes, are emergency services still sent some sort of notification?

I have an iPhone 14.

The published information from the apple website (https://support.apple.com/en-us/HT208076) says:

1) "When Call with 5 Button Presses is turned on and you try to make an emergency call, your iPhone begins a countdown and sounds an alert. After the countdown ends, your iPhone automatically calls emergency services."

2) "If you start the countdown by accident, you can cancel. On iPhone 8 or later, release the side button and volume button before the countdown ends."

This makes it seem as though emergency services are not notified if I cancel the SOS before the countdown finishes.

When I accidentally initiate an emergency SOS (usually via the Call with 5 Button Presses functionality) and press cancel before the countdown finishes, I still later receive a notification that says "iPhone Initiated Emergency SOS at..." This makes it seem as though something still was externally sent to someone despite my having canceled the countdown; like some sort of non-text, non-call notification.

Additionally, in the past, I remember that I cancelled a countdown before it finished, but the day after, I received a call from a personal number I didn't recognize telling me that I had triggered an emergency SOS and they asked if I was in a safe place, etc. Based on that memory, it seems that, while cancelling before the countdown finishes does prevent a call, it does not prevent a notification to emergency services. It is worth noting that this has only occured once. I have accidentally triggered the emergency SOS a few times since then, and I have not received any such calls checking in on me after those cancelations.

So, with all that said, here is my question:

Would emergency services still be notified in any way if an SOS had been initiated, even if the SOS was cancelled before the countdown finished?
