That’s an interesting way to look at it. I can kind of see that. Thanks!

I think in practice the compressor blades are closer to perpendicular to the flow than the exhaust turbine ones. It's also important that there is a larger volume of gas leaving the engine than going in as it expands when the fuel heats it. So while the pressure is the same the energy is greater on the turbine side due to the greater volume so it has power to run the compressor as well as fly the plane.
