I won on autoclaim in my 1st game of 4-player -- I have no idea why

This is the game.  My green opponent had so many more pieces than I.  Why did I win on autoclaim?   Thanks!

basically the game auto resign, giving first place 20 points. Whoever has the most points wins at the end, regardless if you got checkmated first. you ended with 41, your opponent had 20, and since they got first they got +20 points, which means they had a total of 40 points.

in the end: yellow = 0, blue = 40, green = 40, red(you) = 41

you got the most points so you win. The point of auto claim is to claim a win by resigning. Ironic i know.

Thanks!  Are you saying that (1) The result was correct;  and (2) The autoclaim happened because I had 41 points and Green had 20 at the time of autoclaim?  So he would have won, but the maximum he could get was 20 for checkmating me -- which means he would have had only 40 points maximum by checkmating me.  So he acknowledged that he would "win" but resigned because I would have had 41 points to his 40?
