Law of physic still applies... front wears faster. The reason is front brakes does 75 to 80% of the job.

I think the dealer did you a great service... by doing both at the same time, they eliminate you needing to come in the second time for the rear.
There is a reason why front brake rotors are massive compared to the back... because the front does all the work.
When under ABS and ETS, they will grab whichever wheel they deem necessary with more force to keep the car under control... but this mode is used only when you need it so it is very minor wear to the rear pads.

No, as Tiger pointed out, the laws of physics still apply. When going down the road forwards and stepping on the brake, the weight of the car is transferred to the front axle. This means the front brakes do the majority of the work and hence wear faster.
If the pressure applied to the rear was equal as you suggested, the rear brakes would lock up, which isn't desirable.
