They know this, but they have it in the terms to keep dishonest people from sending in crappy phones that do not work, are broken, etc..
They legally can't just say "sorry your phone doesn't meet the requirements, is broken, or what ever" and call it a day. If pressed, they are required to show proof of such findings, and return the phone, as it is still YOUR legal property. No contract can change that unless the contract is fulfilled on their end, meaning they give you the credit, which then, and only then will the device become their property to do with as they choose.
