I always shoot with both eyes open. That's nothing new. I'd guess in MD's scenario, he made shot more because he's a wing shooter and it was more instinctive pointing than it was using the scope reticle. Anyway, there's certainly more than one way to skin a cat and if it works for you, have at it. Pennsylvania hunters are looked down on pretty good on this forum, so I'm sure my opinion is worth dog schit anyway.
I think being a wingshooter sure might have something to do with it, because I do tend to shoot with both eyes open. (I also got a LOT of practice shooting running game with a rifle when young, due to hunting jackrabbits a lot during winter.)
