Not quite. All AWD Subarus (i.e. except the BRZ) have one output shaft out of the engine, 3 out of the transmission/transaxle (2 to the front tires, 1 to the rear diff), and 2 out of the rear diff. Torque split varies between models and years with most near the 60/40 you quote, but the only one (in the US, anyway) that can send 100% torque to either end is the STI with DCCD on full lock.
