I don't think it's the point though. If you watch a next time does this, the aim is to draw 3 or 4 of our players out to press the ball. Their invention and quality on the ball from there on will dictate how successful they are but there is definitely method in why the do it.
For example if they manage to draw 4 of our players to go after the ball, especially with the new goal kick rule then the keeper hoofs it straight towards Morrison and Flint then the likelihood is that their defensive midfielders are more likely to collect the second ball unchallenged.
