In my experience that isn't what it feels like at all. Copywriting is just as much about iteration as software, and as a copywriter you can expect half a dozen or more people to monkey with your work. Sometimes they'll make it worse, sometimes better, but they're always going to change things. And on subsequent reads you will too, if you're any good.

Also, for what it's worth, your examples all beg the question. There's nothing in the blog to indicate that Jesse's changes had a measurable impact on the copy one way or the other.
