 I think it's unusual here that he specifically mentions never having submitted a book with their names in it. I had never submitted a book that had their names in it. So I'm willing to bet there's something going on here where he's maybe shared an informal draft or something he's handwritten before that had these names in it. And he's using the word submitted as a safeguard against the accusations. So this is where it's really important to be able to see this kind of new word come out which he hasn't used before. Being able to hear between the lines, not just see between them is such an important skill. We always talk about behavioral changes, but we're also looking for syntax changes like how is somebody's word choice changed throughout a conversation.
