Does using Android Instant Apps count as installation on Play store? As I saw yesterday, Google I/O 2016 Keynotes with an awesome release of many new features.

One of the best feature which I like most as an Android Developer that is Android Instant Apps. 


  The new Android Instant apps lets you access apps from anywhere without installing. It will let you run Android apps as seamlessly as loading a web page. And, it is compatible all the way back to Jelly Bean.


I have a question in my mind that, if it will be accessed without installing then will it be counted as installation on Play Store? And if it won't, then what is the meaning to use it from the developer side. What will be the benefit to the developer?

P.S. I don't oppose this feature, just want to know how it will work.
Quoting from XDA (emphasis supplied)



  Android Instant Apps is an evolution to the way Android has done applications traditionally. Rather than downloading a full-blown application, Instant Apps allows users to “stream” apps to try it out (in reality, it’s a partial code download), without going through the hassle of downloading and installing it



So, if it is a partial download for users to try it out, it logically won't count as installation


  If Play store will not count then what is the meaning to use it from developer side. What will be benefit to the developer?



This allows app developers to reach out to an even wider audience, as they can now project a native Android app experience to the end user with something as simple as a URL: click and you’re in the app
What makes Instant Apps good for the developer outside of the increase in app range is that they don’t need to build a whole different app. Devs do need to update their existing Android apps in order to get the advantage of the Instant Apps functionality....
Android Instant Apps extends all the way back to Android Jellybean, so you aren’t restricted to only a handful of users on the latest Android version. 


From a developer perspective, I suppose that Firebase Analytics also announced yesterday, will be integrated with this. Other features of Firebase Analytics:


Instead of focusing on page views, impressions or sessions, developers can see what users are doing inside the app, how paid advertising campaigns are performing with cross-network attribution and where users are coming from
Defining audiences
Better crash reporting
Notifications and Dynamic Links to to help developers grow and re-engage app user bases
Storage- Google’s cloud-to-device push messaging service Google Cloud Messaging (GCM) is being integrated into Firebase’ s backend and has been renamed as Firebase Cloud Messaging (FCM)
Monetization- AdMob has been integrated into Firebase
