In my opinion, you may be half right. My logic says You can not start a new
vehicle with a pop-start with a 'completely ' dead 12v battery.
But thinking a little more i also have my doubts; since the alternator once is
spinning due to pop-start, is ready/can to produce electricity, which in both
cases would energize the entire electronics on board, by consequence produce
sparks and start the ICE machine. But me doubt comes with a completely dead
battery (0volts) not sure if the alternator control cable (exite cable) could
induce any curret so it start producing energy.
If that is not true, it would only take more time to start a newer vehicle.
Also, usually batteries never get to 0v and it would depend on how fine and
robust the car's electronics is, by letting all this process to happen with
very little voltage (power)
Just like you said: the only power needed to produce a spark. On newer
vehicles would be: ...to produce the spark and efficiently power all the needed
electronics to make the engine work properly. And that some times may be a
considerable amount of power.
