She has since issued a statement defending her performance saying she knew she had little chance of winning if she went head-to-head with the other competitors doing traditional/textbook/standard moves. So she said she made up all original moves of her own.
This would seem like a sprinter saying "I knew I really didn't have much shot of winning, so I decided to do my own thing and run sideways".
As a side note, even the "good" breakdancing didn't look that great. I saw better breakdancing in the 80s.
