What happens when you accidentally define a convection thermal load to the same surface twice?

Some of our models have a million heat sinks and other surfaces that have convection cooling on them. I was running a simulation and at one point realized that I had defined a convection cooling on a surface twice by accident. I was wondering how SW Simulation deals with this. Does it provide twice the cooling? Or is the dominant convection cooling what ends up making the difference?
