It's literally logic that will be followed extremely, anally literally. No scientific language gets close to being that literal - normally, you are always going to keep the author's view/point in mind as you read. If you were to accidentally remove a random "not" from scientific writing (as happens), we can usually realize what the author meant. (With rare exceptions, if we are particularly unfamiliar with the topic.)

With code, on the other hand, code doesn't have a "point of view". It will just do whatever you wrote, completely literally. The shorter the expressions, lines, etc, the better.
