No, I really don't think it is clear. The arguments cited are things like "everyone should learn to code because computers are so important," or "everyone should learn to code because it can make any task quicker." It's coding for its own sake, or for the direct benefits of being able to use a computer better. In terms of the real educational benefit, it's got nothing to do with what you do the computer and everything to do with what you accidentally do to your mind in the process.
