Eagles Over the Kennebec

I suspect this is part of your writing process, but what does it mean that we have an outtake chapter ten (and fifteen) and a chapter ten? Would they normally be braided together to become the final chapter ten, or would one displace the other? I have a feeling that outtake means literally we tried writing it this way, then decided to do it another way, but... asking is better than guessing, eh? Thanks!
