Still looks like two pedals to me, just one you push to the side. Not sure if this change is really necessary though, I don't think I've ever confused the pedals in 30+ years of driving. Maybe some people shouldn't be in control of a vehicle.
Another thought, with regen braking on the A-pedal more people will get used to doing most of their stopping by letting off the pedal, possibly further reducing any potential "natural" reaction to push down to stop.
