A skilled copywriter will easily "tweak" the text so that it looks more like it was written by a human. Honestly, that's what it looks like the most to me.
This also could be the case. But if the author is going through the trouble of doing some re-writing, that's OK with me personally, as it means they at least put some thought & time into it. If just one or two words are changed, they add the words
"I personally believe" at the beginning, or they add extra punctuation or something cheesy, that's still bad.
That's Symmetrick Ratimov was doing but for the OP, we will never know.
