I think it may be as simple as the terms "goals" vs. "signs." Many of the examples given in the book are things like "By next month, she will have initiated a phone call with me" type of things. or "He will stop using the 'D-word' in our conversations." I think those are fine as "demonstrable SIGNS that she/he is making a move back towards the marriage," and since DBing is all about "doing what works," we ARE to note which things are yielding results (and then keeping them up, and nixing things that don't).
But GOALS to me should be about OURSELVES, and things that WE can control.
