This reason is not stated in the Stack Exchange post, and I believe it’s inaccurate (although, I am not a lawyer either). I think the reason is that you are reading the original implementation to write your own, so you are some kind of a compiler, or translator (as for human spoken languages). As such, what you write is mostly the other person’s work, so you should not claim copyright about it. However, if you are writing a computer program based on the description of the algorithm that you would find in a peer-reviewed scientific paper (that’s what you should be doing, because the paper will prove to you that the algorithm is correct and efficient at solving the problem), then it’s a different story, because copying mathematical expressions is OK (it is proven that it’s the only correct outcome, so there’s no copyright to claim here).
