Different assists at different regionals?

So I was watching a live stream yesterday of several matches at either the Alamo Regional or the Southfield District Competition (I was alternating) and noticed that the way that they were giving alliances credit for assists was weird. They would give alliances credit for assists even if the robots were passing the ball to each other in the same zone (for example robot to robot in red only, or robot to robot in white only), and even noticed that they would give an alliance credit for 3 assists even if all of the robots passed the ball to each other while all remaining in the same zone, but I assumed that there was a rule change of some sort that the referees knew about. Then I was watching a live stream of the Inland Empire Regional today and saw the same thing happen, but the alliance got no credit for any assists. Did any one else notice this?
