Analysis
When the "Click Me" button is pressed, it sends a command to the Sprite "mymessage" telling it to go to the label "start". At the label the text animation begins, and when the animation stops (at Frame 30) there is an action inside the Sprite telling the main timeline to go to the next Scene and play. By using the gotoAndPlay() action - you can set different Targets to send commands from the main timeline to a Sprite and from the Sprite back to the main timeline.
