Did the rookies get this right?

4-42-5 c. The throw-in team commits a throw-in violation.

Consequently, a kick ball by team A doesn't end Team A's alternating possession throw in. So they don't lose the arrow. They keep the arrow, but team B gets the throw-in for the kick ball violation.

6-4-5 The opportunity to make an alternating-possession throw-in is lost if the throw-in team violates.

As the other rules help us interpret what violations are being referred to, we can deduce from 4-42-5 c that it's only throw-in violations.

Case Book 6.4.5 Situation A.

4-42-5 tells us how a throw-in ends. If an A/P throw-in ends we reverse the arrow. But that is not the only time we reverse the arrow. 6-4-5 gives us another time. The Case Book play 6.4.5A even tells us that a violation by Team A during an A/P throw-in is the only way a team loses its turn under the procedure.

If the throw-in ends as described in 4-42-5 then they used their opportunity and they did not lose it. 6-4-5 is a way (and the only way) to lose the arrow without completing the throw-in.
