yeah -- video is marked as private ... but ...
to use animated layer order, the groups whose order you want to change all have to be in one group and it's that top level group that needs to have animated layer order checked.
IOW:
Main Group (is that the group you've called "All"??)
>Elevator
>Girl
>Motorcycle
Timeline (not frame 0): change the order (e.g.):
>Motorcycle
>Girl
>Elevator
Note that if you have smartbone actions that also change layer order (or have a layer order keyframe) in the Main group that will mess things up

[edit:] ok - video is now there: -- nope - you can't move Girl OUT of vytah... probably easiest is to restructure the groups so that the elevator doors and elevator interior are separate (there are other approaches if that doesn't help)
