The writing is merely how to you transmit the logic.
Take the following:

The funny this is that the same is also true for mathematics.
Mathematicians writing proofs and theorems are communicating with other people, not (usually) with machines.
Mathematical notation is s means of human-to-human communication. Yet anything but the most trivial math soon becomes inscrutable to the untrained. As far as I can tell, mathematicians are mostly happy with this. The language used allows for precise, compact expression of complex (i.e structured) ideas. That understanding requires training and rigor is not considered inherently bad.
For whatever reasons the same terseness and concision is derided by many programmers who seem to believe that ease of understanding by the moderately skilled is highly important.
And I agree with that. The best way to get better at something is to do it. Other things can help you along and accelerate your improvement, but they don't work on their own. You have to do it.
Writing requires "logicking out" the likely responses of the reader - and the pseudologic of parsing by the human brain (see Dan Ariely's "Predictably Irrational: The Hidden Forces that Shape Our Decisions").
The old 'write down how to tie shoes' or 'write down how to make a peanut butter and jelly sandwich' projects show just how hard it can be to pin down exactly what needs to be done to do seemingly simple tasks.
