5.4.3 situation

[bbsbvb83]

I am trying to locate the following case book situation in the 2019 - 2020 NFHS Case Book.

SITUATION: Team A serves the ball into the net, then requests a time-out. When both teams return to the court, the coach of Team B asks for the serving order of his/her team. The second referee places Team B in the wrong serving order. The error is not discovered until Team B has won points with an improper server. Prior to Team A serving, the scorer notifies the referees that Team B had an improper server. After conferring with the second referee, the first referee corrects Team B's serving order, cancels the four points scored with the improper server, and Team B serves with the proper server.
RULING: Correct procedure.
COMMENT: The first referee may correct an error by a member of the officiating crew provided the correction occurs before the opposing team contacts the ball for the serve.

This was listed as 5.4.3 SITUATION D in the 2018 - 2019 case book. Has the NFHS moved or deleted the case play? If it has been deleted, does this mean the interpretation is no longer valid?
