In Rugby League, performing a "40-20" is punished by a free kick for the opposing team.

The statement is false because in rugby league, performing a 40-20 (a kick that gains significant territory from behind the 40-meter line and finds touch within the opposing team's 20-meter area) is actually rewarded, not punished, by a change of possession. The team that achieves a 40-20 kick is awarded a scrum feed and gains possession of the ball, allowing them a valuable attacking opportunity.
