From the looks of it, the dressed and undressed geishas are two different actors rather than two frames of the same actor.

When the geisha "opens", it plays the animation (which loops, according to the defs). When it closes, it swaps it with the "closed" actor. When it swaps back to the "open" actor, for some reason it plays the animation where it was last cut off rather than animating from the beginning frame.

That's my theory.
