I think he can have a role in specific games in midfield, just like how for example Real Madrid have used Pepe as a DM in the past. I'm sure Hodgson was just trying it out and isnt looking to play that way every game, but if England were going to play a huge game against a top side he might want to try it in the future and Jones might be the best fit for the role - even though he's definitely not perfect for it as there are midfielders who read the game defensively better than he does, but physically he's a good fit.
You would also need to balance the team around having that defender there - Delph on the left and Henderson on the right would seem to help him a lot defensively but it pretty much left all the responsibility for creating something on Rooney, and when you just have to deal with 1 player its a lot easier to do.
