Absolutely true. No one argues (do they) that the two are not necessarily the same.


So how do we possibly get from this

What if one official signals a block and the other signals a player control foul, then what do we do?

to this?

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)

The question doesn't contain the word charge.
The case doesn't contain the words player control.

Let alone obligation based on signals which may or may not mean the same thing.
