If that's all it was, they could achieve the same thing by using cylinder head materials that either reject the heat or else get hot and stay hot...also does nothing for heat lost through cylinder walls or in to the piston.
I would think it's a case of capturing more of the expanding gasses force...which you could do with a much longer stroke. Of course it wouldn't rev worth poop, and have to deal with more side forces, but whatever...
