I was concerned about this too, but I re-read and noted "when it is not obvious". I'm taking this to mean that perception rolls to determine LOC wouldn't be needed in most cases - even if someone is 34 meters away (17 hex), if you already know they are there (they are chanting loudly, firing guns, hitting your buddy etc) and there isn't any obstacles between you and them, a perception check wouldn't be needed.
... at least that is how I understood it, I could be wrong.
