The article is confusingly worded. I think Google's announcement is more clear [1].
My read is:
* Developers using Google to process payments should expect to go from a 30% fee to a 25% fee (20% service fee + 5% billing fee).
* Subscriptions will now have a 15% fee (10% service fee + 5% billing fee)
* Some Third Party App Stores will be easier to install

Google's announcement is also confusingly written, but I believe your interpretation to be mostly correct as best I can tell.
There's a lot of added complexity because of the <1M plan which isn't new, which put the cut at 15% for under 1M of revenue. Also if you participate in whatever these confusing programs are transactions from brand new installs of your app will be only 20% but transactions from existing installs (before the change) will be 25%...
Ugh
