Vincent, the use of verbless sentences is a longstanding and legitimate method in prose fiction. It's often overdone, it doesn't work for you here and may not work overall, but it doesn't make Loren Coleman inept. I'm speaking as an editor here, and as someone who hasn't read these books.
It is probably a good thing that I am not an editor then, because I would have sent the manuscript back and asked the author to complete his sentences, or otherwise indicate that such incomplete sentences are dialogue or clearly shown to be a character's thoughts, and not the thought processes of the narrator.
Maybe I don't read enough modern books, but I found the technique distracting - just like I found Roland Green's use of "wit" and its variations distracting. Using incomplete sentences once in a while works but using it every single page detracts from the effectiveness of the technique.
I have seen the technique before. I just think there are less jarring ways to write a story. Of course, despite all my reading, this is the first time I have encountered this technique used to such excess.
