Does this constitute as a roll over?

I have written many posts about Parker's unwillingness to roll over. He finally mastered the tummy to back roll out of pure hatered of being on his belly. He has yet to roll from back to tummy. I am confident that he has the ability to roll in both directions, I just think he doesn't want to.

So I ask, does sleeping on his side constitute a roll over from back to belly? I am saying yes it does!
