I believe we are talking about slightly different things. Yes if they thermally coupled the body to the processor, then a small patch of the body would get very hot, burning the user.
However, the fact that the aluminum gets hot during prolonged use means that it is acting as a heat sink and cooling the CPU compared to a body made of plastic. Thermodynamics, it's the law!
