If it helps, I used to edit for DP up until a few weeks back. All work goes through a senior editor who monitors the editors' progress. So although a novel can be passed between two or three editors, it's still goes back to the Senior Editor to be evaluated at each stage. With the edits I've done, any recommendations I had would be addressed by the author and then checked by the next editor. One novel won't see the same editor again, but an author who has a series etc will usually stay with the same set of editors who are familiar with their style. Or, as a contracted editor, that's how I saw work handled.
There's a lot of paperwork with the edits, with detailed notes passed between editor and editor. I'd give the script two sweeps before passing it on: an intial read with minor notes, then a major edit after I was familiar with the novel.
The constant monitoring allows the Senior Editors to keep a track on editor quality. It does give you a big brother feel (as an editor), but I can understand the need to not let quality slip over a couple of novels before anyone notices.
