How to interpret check for background migrations

Hi,
I’m uncertain how to interpret the output for the check mentioned in the upgrade guide for running background migrations.

Is this, 0 in queue and 1 processed? Or 0 processed/queued and 1 Worker ready for action?

Ok, second output now changed to 0 as well. So I guess it was 0 in queue and 1 being processed.

Should maybe be mentioned in the upgrade guide
