That's the $64,000.00 question.
Basketball Points of Emphasis - 2017-18
2. Team control, throw-in. The relevance of team control during a throw-in only applies when a member of the throw- in team fouls. Such fouls shall be ruled team control fouls. Team control during a throw-in is NOT intended to be the same as player control/team control inbounds. Team control inbounds is established when a player from either team who has inbound status gains control of the ball. During the throw-in, 10-seconds, 3-seconds, frontcourt status, backcourt status, closely guarded, etc., are NOT factors as there has yet to be player control/team control obtained inbounds.
Now, how are those without access to a 2017-18 rulebook supposed to know this?
By the oral tradition of young basketball officials sitting around a campfire listening to stories about old Points of Emphasis from old, grizzled, veteran officials?
