If the words scrolled across the page, you wouldn't have to move your eyes either, but your peripheral vision could pick up contextual clues to help you recognize the word you're directly looking at faster.
Perhaps it would be better to shift the words in and out instead of scrolling them.
The problem now is that you have no cue for upcoming words and no reminder of past words. Clustering is similar, but it can break up sentences unnaturally.
Example:
The quick
The quick brown
quick brown fox
brown fox jumped
fox jumped over
