 * Test the execution order of actions within different movieClips
 *
 * set a variable with a new value under _root, then set it again under anther movieClip.
 *   the variable will only record the later assignment. Checking the final result of the
 *   variable will tell us which action(assignment) is executed first.
 *
 * Expected result is:
 *   In the frame placing mc_red,  actions in mc_red is executed *after* actions in _root
 *   In subsequent frames, actions in mc_red is executed *before* actions in _root
