He is a representative of their product afterall. He is going after the cup in this series and just money in the truck series and the nationwide series.
This is where my opinion comes into play. Truck series drivers should only race in truck, nationwide should only race in nationwide, and sprint cup should only be racing in sprint cup. It should make no difference that they own teams in other series. That is why they hire drivers to drive those vehicles.
