What cards return when you resume a paused "practice rem in this document without spaced repetition" queue?

When you ‘practice rem in a document (without spaced repetition)’ and then leave and decide to go back to it, there’s an option that offers you to continue from that checkpoint you had stopped at previously. I just wanted to confirm that this will ensure that I will cover all the card i did not cover before? Because i noticed that some cards that i would’ve done before appears again (even though i choose the option of practicing without spaced repetition).

When you return to a queue that you had previously paused, you should only be tested on cards that you had not yet practiced. Before resuming a paused queue, you’ll see a prompt indicating the number of cards that you have remaining.
