Had a game tonight, 3 man crew. I am the trail official, ball goes out of bounds in front court on endline on opposite side of lead between 3pt line and sideline. Lead doesn't blow his whistle and after a hesitation C does. During halftime I asked the official that had been the lead why he didn't blow his whistle, since the endline was his line. He said that he was taught as lead that he only has the endline from 3pt line to 3pt line, and that he was not supposed to call anything that went out on the endline between the arc and the sideline, on either side.
I know that the leads primary area on ballside, on the court, is inside the arc to the basket and he is not looking to call fouls, violations, 3pt goals, etc, that occur ballside between the arc and the sideline. But if the ball goes out of bounds on the endline, I thought that was his line exclusively (just as the trail has the sideline and the division line and the C has the opposite sideline). I was taught if the ball goes out on the endline, even on the other side of the court, that the lead is the one and only whistle, and if he is unsure of the direction then he looks to the C for help.
What is the correct procedure?

L has the entire endline
