I just took that clip into iMovie, where I can slow it down to frame by frame. It definitely seems as if the first curtain is closing and then opening again, but it sure is fast. When you listen to it frame by frame, there are quite a few shutter sounds going on.

Could it be that the physical shutter sequence is not altered, but the electronic shutter makes it possible to adjust the timing of the actions?

For example, the initial curtain could close and reopen as quickly as possible, before the camera/sensor is ready to shoot. That might give a few milliseconds for things to settle down before the electronic shutter starts exposure.
