Ok, let's see...
Our cars are originally designed to get the choke operating with the engine temperature from the intake crossover. That's actually the CORRECT way to set the choke control since is the real temperature reference.
The electric choke source is a help to get the engine at low iddle cam position on carb cam a bit faster than just the engine temperature, helping to the bimetalic coil spring to get heat with the heating element ( resistor ). With the electric assist you can get your iddle speed in, lets say 3 or 4 minutes, instead 7 or 8 minutes. But engine temp is still working in it. Mixture was getting already warm on that time.
This is of course if you did't blocked the crossover provisions on heads.
If you have had your car already operating, engine already got warm allong the day. If you let the key in ACC afew minutes then start up the engine, won't affect anything, since the engine was already warm. The car will start up correctly at iddling with the choke down. No matter if choke was being sourced from the electric assistance. Engine is already warm from the regular operation and will iddle nicelly.
Now, if engine is cold from overnight and you let the key in ACC for some time, the choke will be open due the heating element sourced from the electric assistance, and not from the engine temp. If this happens, the fast iddle cam on carb won't get in, so if you start up the engine, will iddle like you don't have choke, cold mixture, iddling erratically. Mostly sure will need to crank the engine several times, or giving throttle to keep the engine running untill get the operating temperature. Simply like you don't have choke.
This happens if you let the key in RUN too of course, but that's a default. As mentioned, this was corrected on later years with a oil sender with a built in switch, able to switch on the power just when sense the oil, so with engine running. With this sender, you can feed from the run circuit any device but just power on when engine is running, the choke for example.
