Because heart first transfer impure blood to lungs and then lungs to heart and after that heart transfer oxigenated blood to all body parts. That is why it is called double circulation of blood.

The majority of mammals (including humans) utilize a double circulatory system. This means we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.
