Oh dear oh dear, the engines don't turn different ways on different wings, the engines have counter rotating shafts as in the LP turns one way and the HP turns the other. This is the first counter rotating Hi Bypass ratio turbine engines I have come across on modern aircraft.
Technically speaking it is contra rotating rather than counter rotating, which is what I thought the originator was alluding too, perhaps not, so I'll leave it to the more technically adept people who know more!
