529 distributions are considered support from parent or student from a tax perspective?

I read that article a few years ago, and it made my head hurt. I don’t know if the IRS has made a determination on this, but to me common sense says that if the student owns the 529 account, money from the account counts as the student providing his own support. If the 529 account is owned by someone else, money from the account is not the student providing his own support.
