"Brevity is the soul of wit."
― William Shakespeare, Hamlet
Sure: Being brief is a good thing. Shorter is generally better and easier to read. It should be a goal when writing, especially technical and scientific writing, to express the idea as quickly and crisply as possible.
I do find that when I edit my writing, it often gets a little bit shorter as some clunky phrases or repeated wording turn out to be unnecessary and get removed. And redundant references are in fact a pitfall that things might fall out-of-synch when edited. But I broadly doubt that's a top-level priority for anyone when structuring their writing. The top goal is to be clear and expressive, and not elaborate more than is necessary.
That said, there is a practice in software development called refactoring which pretty much boils down to exactly the OP's intuition here -- take existing, functional program code, and edit it for readability and maintainability. In most cases this leaves the code shorter than when it started, and indeed more robust in terms of attack-surface for bugs and broken references.
In computer programming and software design, code refactoring is the
process of restructuring existing computer code—changing the
factoring—without changing its external behavior. Refactoring is
intended to improve the design, structure, and/or implementation of
the software (its non-functional attributes), while preserving its
functionality. Potential advantages of refactoring may include
improved code readability and reduced complexity...
