He never makes that claim. He focuses on whether or not a tweet is copyrightable as a body of work. He never brings up or implies that a person's timeline might be something more than the sum of the individual tweets. His answer to the question is no for various reasons.

However, we intuitively know that words and sentences are not the end product of writing and don't base copyrightability on the basis of words and sentences being copyrightable.
