Second situation was not an IAABO interpretation (it was my own curious question) but basically the same thing regarding and a plane boundary delay "warning" after the inbound play where the defender crosses the plane and slaps the ball (technical foul), or the inbounder (intentional foul), with no previous delay warning (of any type) such that the next delay (of any type) is a technical foul. Does an official really instruct the scorekeeper write a delay warning, a warning that really wasn't given, down in the book?

Are either, or both, of these warnings actually "issued", or are they just understood to exist?

According to Case Book 9.2.10 SITUATION A we do:

A1 is out of bounds for a throw-in. B1 reaches through the boundary plane and knocks the ball out of A1’s hands. Team B has not been warned previously for a throw-in plane infraction.

B1 is charged with a technical foul and it also results in the official having a team warning recorded and reported to the head coach.
