Expert Handling is an action. 1 single complete action. From "Perform".... to "ship" it is a single action.
During expert handling, it tells you to perform a FREE Barrel Roll action. This action is free (does not count towards the one action during your perform action step). The Barrel Roll inside expert handling is a complete action. Either one (and both) are actions according to the rules, with all rules applying to actions affecting BOTH expert handling, and barrel roll.
To clarify, you cannot do this if you already performed a barrel roll? Because that would perform X2 of the same action?
