They are pretty clear, even for an ignorant like me.
I created a backup
I switched my laptop off, then on
I started the restore utility
I ticked the “just verification, no restore” option (not sure about the exact text, but should be clear enough)
I got to the “Qubes to restore” screen
Now there is one point that puts me in doubt.
Is my backup OK?
Has it been checked out already?
Or should I select all qubes for restore, and click “Next”, and only then will then utility check each qube backup and let me know if everything is fine?
You have to go through it like you are restoring, which means you will have to check the qubes you want to verify and click next. The only difference between the two options UX-wise is that when you are verifying only, the qubes are verified and not restored.
This may be a good place to start a UX ticket in the issue tracker because of the ambiguity.
