It feels kind if dumb to see such configuration and I have worries If I drain small 12v battery by using car with engine off It wouldn't start..

Well in a technical sense you are also right, since the contactor for the main battery gets power from the 12v (albeit it's not a big load) Meaning if the 12v is completely dead the hv battery will not switch on and the motor will not start.
