Question What is the Oygen saturation of systemic venous blood??

I got a question..
Goljan RR ( Page 3 third ed, under the graph ) states that in a normal oxygen binding curve, only 50% of its oxygen is released to the tissues, implying that the oxygen saturation of the venous blood is 50%
But kaplan, Resp Physio ( Page 168, 2011 ed) sates that, the systemic venous blood is 75% saturated.. It sounds more logical, as for the binding of O2 to the third oxygen binding site the minimal Po2 shld be 40 mmHg, (therefore making oxygen 75% saturated), which is exactly what the Po2 of venous blood is.

Am i interpreting goljans' statement wrong!?
