Most of my statements were opinions, which are not provable or dis-provable therefore.

However, MFI injects fuel only into the cylinder that needs it. Have you ever studied the inner workings of an MFI pump? They have a cam like the cam actuating the intake and exhaust valves. These push plungers in the right sequence and at the right time to increase the pressure in the fuel lines to overcome the MFI injector's spring loaded valve and spray fuel just in front of the intake port.

Then there is the 3D space cam that works with the flyweights and throttle position and barometric compensator and the thermostat to change the fuel delivery based on load, engine speed, air pressure, etc.
