No, the incorrect OOB was on one of the Romanian gymnasts. There was no category for incorrect OOB in the appeal form, so the Romanian coach appealed on a different category and the appeal was denied.

Chiles' appeal was for elements that weren't scored and the coach admitted not expecting the appeal to actually do anything.

When they modified Chiles' score, Romanians were all like "of course Americans get their appeal heard and our gymnast is pushed off the podium". Then there was the court ruling to reset the score back and Americans were all like "of course they give the white girl the bronze back and push the black girl off the podium". Now it doesn't help that a lot of Romanian idiots started hurling racist comments all over social media during the whole mess.

Overall, the Olympic committee screwed up and the gymnasts were the ones to suffer for it. The Romanian team asked to give bronze to both (they can give 3 bronze medals I believe), but for some reason that's not what was decided in the end.
