It bypasses some of the filters and changes the counts. Stand alone research will not send questionable count changes to the drastic count report. That's why "% of scans within task list" is a metric. Target doesn't want counts changed through stand alone except for working the drastic count report, after a new POG set (since it doesn't bypass the "new item" or "received within last 48 hours" filters), and if you absolutely know you don't have the item.
