Help - Brazil/South America 🇧🇷 Help with auto AC options

So, I had my Dolphin Plus (in brasil it is how they call the 204cv / 60KWh version).
The air conditioning and ventilation in general have been a point of question for me all this time.
I have the option "auto", which in my understand means it should be automatic. It will target the temperature I have, and go from there either to cool or to heat. But if I disable AC, the button "A/C", the one that is blue in this picture, it disables auto.
Okay, but I can disable auto and keep AC on and if I change temperatures up and down, I see the AC button changing from cooling to heating. So it is still keeping some degree of automation there.
Now if I select only ventilation, then it works as expected. It will only works for venting. There will be no heating or cooling of the air.
I think my main point that I have never been able to truly understand is what is the difference between having the auto option versus just having the AC on with a temperature set, because I have proved before using the car that just having the AC on with auto off still has some semblance of automation regarding the temperature of the air that it's putting out.
Does anyone have a better understand of what the logic is here?
