Just doing some mind-reading here, and we know that's not a good idea....
But I would say that he is trying to lay out what he wants you to think is ok for him to do, by telling you what it is ok for you to do. It's just drivel.
I wouldn't respond to the email at all. If he wants to let his imagination work overtime, that's his problem. If he were to actually ask you a direct question then you might answer it!
