I can mostly handle a 50 GB patch, but buying a physical copy, just so it can give me access to another 50 GB of 4K assets download kinda ruins the point of having a console.
As said before, who's to say 4K assets would not be included on discs that have space for these to spare?
The article sure doesn't mention the word physical nor disc at all and could be interpreted in only concerning itself with how digital purchases are downloaded on the Xbox One X.
