I've tested this a few times using your opening and closing door tutorials and the door opens, but doesn't close again. I can keep opening it wider and wider. If I tweak and put in engine:pause game in the top of the list of the cutscene, then the door will open in the opposite direction, but it will close again.
Tested in Unity 4.6.3 AC 1.42c, and in Unity 4.6.4 AC 1.43a

The check box, 'wait until finished' is not my preference though, because I need that pause before the door closes so the player can walk through, rather than being stuck waiting for the door to finish its action.
I hope this helps.
