There's nothing inherently better about the edited version. It's just saying the same thing with synonyms substituted, at a slightly more formal but less personal register. HN comments are not academic text, colloquial turns of phrase are perfectly fine and expected.
I don't know why this is confusing. If I forget to put the "not" qualifier in a sentence, do we agree that it can confuse (or worse, mislead) the reader?
You're saying removing ambiguity does not make it easier to read? You're saying using a word that means nothing like what you meant to say is easier to read than using the correct word?
