The article doesn't show the original context for the photo, but I imagine it's an image of the body after using it, not while the cooler is attached.

Right, but then the question remains why is the lower back cooler in the picture as well. Is the blood flow through ones entire back flow through that area first?
Which of course made me think the correct placement for it would be somewhere with a lot of blood flow near the skin that could be cooled a couple degrees. I was thinking the inner thigh might be a good place, but the device isn't shaped correctly for that, given your just going to cool one side, and cook the other.
If this is using the Peltier Effect the cold surface would be against the skin to cool you, and the hot surface would be pointing out towards the thermal camera which is the opposite of what it shows.
If we take that photo at face value, the device is actually heating the person and yet their skin is somehow cooler (which isn't actually something this device can do anyway, it makes you FEEL cooler, but doesn't actually cool you over a wider area, or worse actuall makes you even hotter as you will sweat less due to misleading signals).
