When you finish an on-demand scan, you get to see the results of the scan and can choose an action. If you choose to ignore a threat you get to see that item again in the following result dialog marked as "(No action taken) [No action possible v]". If I decide to ignore a threat I don't need any further information about it, so it would be nice if it wouldn't show up again, so that I can focus on the important remaining items that really require my attention.
