I agree that doesn't make much sense. The only thing I can think of is that it would "wipe the slate clean" in his mind for some reason so that he could start again, and going back to a dating relationship will feed his desire to be "in love" and to pursue.
I would take it as a good sign that he wants to date you again! That's really excellent news. Focus on that, and don't make it too easy for him. With regard to the divorce, do nothing to help him.
