Not on these two models (the NEX 3n and A3000), it doesn't - they are permanently in electronic first curtain mode. So when an exposure starts, the shutter remains open and instead the sensor is scanned sequentially to capture the image. This is in place of the running of the first shutter curtain. Then, the physical second curtain closes again and reopens to give live view, as you described.

This makes me wonder why we need a physical second shutter curtain. Can't the closing of the second curtain be done in electronics as well? I mean, that's how digital compacts and phone cameras work as well. What's the advantage of a physical shutter?

Because the sensor is too big, and too high resolution, for a global shutter, and global shutters also require other trade-offs.
