I thought the wicketkeeper had to "remain wholly behind the line of the stumps" until either the ball touched the bat, or batsman, or it passed the line of the stumps (or the standard umpire signals dead-ball or wicket falls). If he encroaches before the ball is struck, it should be called a no-ball.
