No, the resistance wire (or ballast resistor) has nothing to do with engaging the starter and/or allowing it to disengage once the engine has started.
The only reason the coil/ignition circuit is even connected to the starter solenoid is to allow the solenoid's "R" terminal to provide full battery voltage to the coil while cranking the engine. That temporarily bypasses the resistance wire (or ballast resistor) for a hotter spark while cranking.
The circuit that engages the starter solenoid is typically a purple wire that is connected to the solenoid "S" terminal. That wire runs back to the "S" or "SOL" terminal on the ignition switch and might pass through a neutral safety switch along the way. This circuit should only have power when the ignition switch is turned to the "start" position.
