The starter relay is only energized when you're starting the car, the ignition obviously needs power from that new "ignition supply relay" when the engine is running as well. Therefore power from the starter relay would not be a good source for activating the new ignition supply relay.

Switched 12V power from the new ignition supply relay is used to supply any portion of the new ignition requiring a switched source of 12V power; the coil, the module, etc..
