When does a card get a MK Qualifier?

There's a PSA 4 Joe Tinker portrait on Ebay right now that has the name Warren in ink on the back with no qualifier. They grading standards say all cards with marks will have the qualifier added. It does not look to be of a high enough grade to achieve a PSA 4 with NQ. Anyone think this might be a mistake?Warren's Joe Tinker Portrait
