Rebellius's 100% loss was overturned solely because the player from China didn't appeal to the judges but instead presented his arguments on the forum.
Rebellius wanted to get a restart for free, citing the previous restart due to generation issues, but it was checked, and there was no restart.
Herolvi posted a report.
Upon seeing the report, Rebellius should have contested it. And it seems he did so successfully, as the report was eventually overturned.
It's just unclear which part of the argument led to this. But I'm not a judge, and it's not my business. I can only draw some conclusions.
You're just a smart guy, but only half. So it's really none of your business. If you can't handle it, don't get involved.
