The official justification given for this change was that "[previous dropped ball procedure often leads to a ‘manufactured’ restart which is ‘exploited’ unfairly (e.g. kicking the ball out for a throw-in deep in the opponents’ half) or an aggressive confrontation. Returning the ball to the team that last played it (had possession) restores what was ‘lost’ when play was stopped, except in the penalty area where it is simpler to return the ball to the goalkeeper. To prevent that team gaining an unfair advantage, all players of both teams, except the player receiving the ball, must be at least 4 m (4.5 yds) away."
