Based on the interpretation, the conflicting preliminary signals (calls) are irreversible.

4.19.8 SITUATION C: A1 drives for a try and jumps and releases the ball.
Contact occurs between A1 and B1 after the release and before airborne shooter
A1 returns one foot to the floor. One official calls a blocking foul on B1 and the
other official calls a charging foul on A1. The try is (a) successful, or (b) not successful.
RULING: Even though airborne shooter A1 committed a charging foul, it
is not a player-control foul because the two fouls result in a double personal foul.
The double foul does not cause the ball to become dead on the try. In (a), the goal
is scored; play is resumed at the point of interruption, which is a throw-in for
Team B from anywhere along the end line. In (b), the point of interruption is a try
in flight; therefore the alternating-possession procedure is used. (4-36)
