When first_open event in Firebase is logged?

I am confused with first_open event in Firebase. Here is the document : Document

first_open: the first time a user launches an app after installing or re-installing it.

This event is not triggered when a user downloads the app onto a device, but instead when he or she first uses it. To see raw download numbers, look in Google Play Developer Console or in iTunesConnect.

However some people from Google said that : Refer this link

The last important distinction is that when existing users migrate to the new version of your app which includes Firebase, they will log a first_open event. And so, even though they are not new users, they log a first_open.

As my understanding, If we update app by Google Play then start app again first_open will be logged ? Is that correct ?

Update :
Firebase version
root/ 

classpath 'com.google.firebase:firebase-plugins:1.1.5'

app/

implementation 'com.google.firebase:firebase-core:16.0.6'
implementation 'com.google.firebase:firebase-messaging:17.3.4'
implementation 'com.google.firebase:firebase-perf:16.2.3'

first_open

the first time a user launches an app after installing or re-installing it.

This event is not triggered when a user downloads the app onto a device, but instead when he or she first uses it. To see raw download numbers, look in Google Play Developer Console or in iTunesConnect.

So I think,

It will not count again if you are updating your app. It will just count when you launch your app first time after installing or re-installing.
