I'm pretty confident after the 2008 camera exploit they engineered the camera to wire the active light directly to the camera power source, which I think is what you're talking about with #3. #1 and #2 seem kind of irrelevant to me. Unless it manually operated (in that case, why not use a physical switch?) it behaves the same as the green indicator light, relies on #3, and after its turned on it's already capturing.
