He's right, but English is also not his first language, and writing like that is pervasive in India.

Yes, except none of the hemes in your body are realistically going to be unbound.

Hemes each bind 4 oxygen molecules, and the bind cooperatively, so each successive oxygen molecule is harder to strip off. This makes it less likely you have a completely unbound heme while there is another one with four O2s attached.

In your inferior vena cava you'll see usual O2 saturations of ~75%. It can get down to ~55% in the coronary sinus, but nowhere near 0 in a physiologically normal state.
