> After app verification, exactly the same.

No, because to install unverified apps the user has to 1) enable developer mode, 2) confirm you aren't being guided, 3) reboot the device, 4) wait 24 hours, 5) enable unverified app installation. You also have to confirm that you are really-really sure with every install. Oh, and that step 5? Google explicitly recommends turning it on for 7 days only.

> It allows installing apps outside a system app store without the user having to enable installing from the app that triggered the install.

... which was already possible, so it is not enabled by app verification.

> You are confusing app verification with a change in how to install unverified apps.

It is two parts of the same thing. App verification exists only to make installing unverified apps difficult. App verification has no reason to exist if installing unverified apps is not restricted.

> No, because to install unverified apps the user has to 1) enable developer mode,

As I said in my first comment, that change is separate from app verification.

> which was already possible, so it is not enabled by app verification

It was not. Read the rest of that sentence beginning with "without."

> App verification has no reason to exist if installing unverified apps is not restricted.

App verification is required to allow installing apps outside a system app store without any warning to the user, as required by the ruling.
