Verbosity adds noise (redundant information), or information that is usually redundant, so you get used to it, so when you see the ~same pattern again, you skim over the things that you think are the same. But then sometimes it isn't quite the same, because of a bug or because the for loop does a decrement rather than an increment, which is lost on you.
Finding the balance between terseness and having a little bit of redundant information is of course very hard.
