I got this from a youtubes comment. Sounds good to me.
The first batch of penalties were all disallowed for encroachment by the taker's team's players moving into the box / 'D' before the ball is kicked. One of them rightly ends up getting booked for this. The second penalty is retaken because the goalie moves forward from his line before the ball is kicked - you're allowed to move along the goal-line, but not off it. You could call the ref pedantic, but he's applying the laws correctly - it's other refs that don't apply this consistently.
