It would've been just like Steam.
You don't need to carry your Xbox One anywhere. Your XBL ID and games would've been accessible on any Xbox One (in the XBL supported countries).
The games were tied to your account. Now after the change, they're not (the physical ones at least), which means that you need the disc to play, because otherwise you could just sell the physical copy while still having access to the version on your HDD.
The gameplay changes due to the cloud remain uneffected.
