Yup, they were exactly the same in the demo.
Seeing as the (LT) precision modifier is one of the top features of this years game and was heavily featured in the demo and LB/manual pitch has been in the game for years it would have been quite noticeable had these been different in the demo.
I've made the mistake of hitting LT when trying to use a precision modifier but the worst I've seen was a guy I was playing against doing it on the goal line going in for a TD. I think he may have been trying to use LT+X to dive over the pile but instead he pitched the ball back as he was crossing the goal line and I recovered.
I felt so bad that I played conservatively on my possession and ended up going 3 and out and punting. His returner muffed the punt and I recovered that as well.
