Don't know what your "dispute" is about, but NF: 2-16-h spells out the 5 requirements necessary for PSK enforcement. What may be helpful is to recall the reasoning behind creating a PSK enforcement. Essentially, that the defensive team had accomplished it's task and had forced the offensive team to relinquish possession by choosing to kick the ball.
Since a kick is a loose ball, and the basic spot for a loose ball foul is the previous spot and repeating the down, the consenus was that considering fouls committed by Team B after the ball had been kicked, being considered loose ball fouls prior to an actual change of team possession, provided an excessve penalty to "B".
The conclusion was that Team "B", although responsible for their foul and should be held accountable by paying a reasonable yardage penalty, should not be deprived of the benefit of forcing Team "A" to relinquish possession of the ball, byt their superior and foul free play. Conversely, it was concluded that Team A, having been defended into deciding to volumtarily give up possession of the ball, did not earn the right to have possession awarded to them because of any foul B committed after the kick "crossed the expanded NZ".
