That means it is his account that is signed into the device as the owner. That can only happen with physical control of the device and cannot be done remotely. If you previously had your account signed in, it would require your password to remove your account, then he could add his account on the Mac.
If you still see the device in your device list, it just means that a service on that device such as iMessage, FaceTime, AppleTV, or Media & Purchases has signed into your account. It does not mean that you are the owner of the device who has their Apple Account signed in at Settings > [name on top]. That is the Apple Account used for Find My and what locks the device to the account.
