It's just an example of how the action list of a command could look. You need to recreate that in your command.
It's a "Set an Integer Value" action, followed by a "Begin a Conditional (If Statement) Block" action, then alternating between "Play a Random Sound" and "Add Else If to Conditional Block" actions (the last Else is a "Condition Else" action instead, though you could make that another "Add Else If to Conditional Block" action if you prefer).
