Mostly correct. The compressor is directly attached to the high pressure turbine (HPT) via the high pressure shaft. The low pressure turbine (the 4 stages aft of the HPT), are directly connected forward to the high bypass fan through the center of the engine via the low pressure shaft. That is, the compressor and the HPT spins independent of the LPT and fan.
