There are also some changes in the text... see paragraph 204.
"The Lead official should be prepared to provide ball-side assistance when the ball and the majority of players are on the Trail's side of the court. Having the Lead move ball-side leaves one half of the court completely uncovered, therefore officials should use this mechanic sparingly and should thoroughly discuss its use during the pregame official's conference. Officials may also want to consult ther state high school association for guidlines regarding the use of this mechanic."
Diagram 11 does stress that the Lead must remember to go back to a 'boxed-in' position after the ball goes back beyond the 3-point line.
And also note that in Paragraph 206 (although it is not highlighted ... maybe it changed last year?) they have adopted the 3-man mechanic for the 2-man game:
"When a player with the ball starts a drive to the basket from an official's primary area, that official has the player and the ball all the way to the basket."
