A "Yes" arrow points right from the "Is this SQL tracked?" diamond to the "Does a SQL plan baseline exist?" diamond, whose "No" arrow points down to the "Create SQL plan baseline" box, which points down to the "Execute this plan" box.

The "Does a SQL plan baseline exist?" diamond "Yes" arrow points right to the "Does plan match plan in baseline?" diamond. This diamond has a "Yes" arrow that points up to the "Execute matched plan" box.
