Analysis of following writing pattern

Is there a name for following writing/dialogue pattern?

We ride into the future. A future where ...

In the world you grew up. A new world with ...

It's just a theory. A game theory.

These make use of rhetorical devices, making sentences shorter and using repetition for emphasis.

Of the rhetorical schemes detailed by Dr. L. Kip Wheeler, associate professor of Carson-Newman University, see the following:

Anapodoton -- deliberately creating a sentence fragment by the omission of a clause: "If only you came with me!" If only students knew what anapodoton was! Good writers never use sentence fragments? Ah, but they can. And they do. When appropriate.

And:

Anadiplosis -- repeating the last word of a clause at the beginning of the next clause. As Nietzsche said, "Talent is an adornment; an adornment is also a concealment." Extended anadiplosis is called Gradatio. For instance, in The Caine Mutiny the captain declares: "Aboard my ship, excellent performance is standard. Standard performance is sub-standard. Sub-standard performance is not allowed." Biblically speaking, St. Paul claims, "We glory in tribulations also, knowing that tribulation worketh patience; and patience, experience; and experience, hope, and hope maketh man not ashamed." On a more mundane level, the character of Yoda states in Star Wars, Episode I: "Fear leads to anger; anger leads to hatred; hatred leads to conflict; conflict leads to suffering." Gradatio creates a rhythmical pattern to carry the reader along the text, even as it establishes a connection between words.
