WP Admin -> Email Templates -> Report

In the report section, how does this work exactly. I see it says “Ordered & clicked from suggestion product in email” as the main header and then in the line where it shows product names it says “Ordered” above it. Is this how many people have clicked products that are shown by the product widget usually as featured products, newest, top rated, etc? Or is this products customers have ordered that in order confirmation emails clicked the product name in the order table? Is there one color for the bar graph for clicked and a different color for ordered (after clicking product in email they placed an order for that product)? Any details is appreciated as in documentation there are no details I can find.
