What happens when the referee and the player do not know the rules?

Barbarians Castle George Cruise scored three conversions in the game, one of them with a heel. Arbitrator Andrea Piardi counted her, although according to the rules he should not have.

Why? Here is a clarification from Nigel Owens: “George was very lucky that his implementation was counted, because a heel strike is not really a strike. Kicking, in rugby rules, is a player kicking the ball with either front of the leg below the knee. I understand that the match is an exhibition match and on the Barbarians field, but according to the rules, such hits do not count .

Recall that on June 25, the “barbarians” under the leadership of John Mulvihill in Gijon will meet with Spain. Initial strike at 22:00 in Kyiv and Moscow, 23:00 in Tbilisi.
