Hard call - I think it signifies the referees assistant has indicated that whilst the ball is not touching the line, technically the curve of the ball is covering the line and Pascal may now proceed. The rest of the routine has yet to be covered in training drills and everyone is eager to find out what should happen next.I've been analysing this, and I have come to the conclusion that it can only mean: "Get ready chaps, I'm about to deliver a set-piece that poses absolutely zero threat to the opposition".
