Before you go into LiveView, the shutter is closed. When you start LiveView the shutter opens to expose the sensor. When you finish LiveView the shutter must close again because the shutter covers the sensor during normal viewing. That's the +1.
For each exposure in LiveView the shutter closes before the exposure. At this point the sensor is cleared to make it ready to record the image. Then the shutter opens and closes for the exposure. The sensor data is recorded and then the shutter opens again to resume LiveView. That's the 2x
For LiveView mirror only makes one cycle regardless of the number of exposures made during LiveView. It flips up out of the way of the sensor at the beginning and flips back down for normal viewfinder use ant the end of LiveView.
