This is about player communication and reaction to that. The problem is that the overlapping support player will be coming from behind so it is not always easy to react in that situation when a pass elsewhere has already been chosen. First of all the support player, who has either made the first pass then made the overlapping run or has overlapped as an attacking option, should be communicating that he/she is making the run. A call of 'HOLD' would indicate to the player that an overlap is coming or 'DAISY'S OUTSIDE' would let the player know where the support is.  Now we are relying on the player in possession to make a pass into the run of the overlapping player or if the defending team has reacted to the move, there will be space in the center where the defenders have moved from. Now the player on the ball either uses the overlap as a decoy or passes down the line. Great for teams that play out from the back.
