Missed the last part of this story...

... a similar incident ocurred in the 1984 Olympic Finn qualifiers. One boat
would win even if he was last, as long as another competitor didn't finish
in the top 10 (or something like that). So he crossed the line early, then
sat on top of his friend for the race, and when he pushed his friend to last
place at the windard mark, retired. This is the basis for IYRU case 34.
