Since she's being sponsored I bet the company has a contractual right to use her name. And, unless there's a clause in that contract that allows her to suspend that arrangement then she couldn't give the IOC exclusive use of her name during the term of the sponsor's contract.
I would bet the company just decided it was less risk to wait a week or two to use the name than it was to roll the dice with potential litigation.
Because it's Slashdot, silly.
