What was taken out if context? It was a scrimmage kick, the ball crossed the neutral zone, Team B fouled before the kick ended. The AR doesn't say which team recovers. If A recovers it obviously doesn't matter, PSK doesn't apply and the penalty is enforced at the previous spot. But if B recovers, the AR says A gets to keep the ball if the foul is within three yards of or behind the neutral zone. That's not right though because PSK should apply since all 4 criteria were met.
