It's counter-intuitive, yes, but if it works how I imagine it to they really are heating the coolant. Ordinarily the coolant would pick up heat from the batteries and move it to a radiator, but in cold weather the coolant is heated to warm the batteries. If you prefer to think of it as the heat exchange medium then you're free to do so or come up with your own more descriptive alternative but for the vast majority of the time it's just there to cool the batteries.
I freely admit that I'm pulling this out of thin air but a quick look on google tells me that the performance in a Tesla is reduced in very cold temperatures. Strapping a heater to the cooling system and adding a valve to divert the coolant away from the radiator (assuming there is one) seems quite an ingenious solution.
