I'd say it's a red-green thing. It's there to give you flexibility with your meal choices that you are already building into your EE days by having red and green free foods at each meal.
So you have your red brekkie, green lunch and red dinner or whatever, and your superfree snacks...and then your syns whenever. You can still have your HEs with your meals, so being able to have potatoes with your steak, for example, is fine.
Are you asking whether you could still do that but then have an EE dinner, kinda thing?
I don't really do EE myself so perhaps someone who does it could suggest how it might work.
