There was a substitution right as stoppage time began and the referee added time for it onto the original four minutes.
As for advancing, not allowing a free header when you're playing with THREE center backs in the last half minute of added time is a great way to start. Don't really care if they drew the fourth-ranked team in the world. This one feels like a loss.
They also had the ball in the corner, and cheaply gave it back. You should ALWAYS get a corner kick out of that, and had they gotten it, most likely they run out the clock.
