I'm wondering if he can even close the dispute on his end through eBay since it's saying he "filed a payment dispute with his payment institution directly". Maybe he would have to go through his bank?


He won't be able to close it through eBay.  He would need to ask his payment provider to do so.  If it is a Chargeback with his bank/card issuer then it may not be possible.
