That's basically it. The combination of HV and a lower kV motor do pull less current for a given power output. They are more efficient because electrical losses are dependent mainly on current draw. A high kV motor on lower voltage can make the same power, but it draws much more current and that high current creates more heat. Heat = lost power.
