I just checked in that hole on the side of the heat sink and inside there is only a smooth surface. I'm feeling like he soldered the bottom part of the module to the heat sink but I'm nowhere near sure on this. I couldn't get my camera to cooperate and focus inside the hole but the video came out a bit better and I posted it above for reference
