Defrost without heat?

As you know, the v-8s have four levers for controlling airflow and heat.

As I understand this system, there are two vents (l&r) which can be opened or closed by the two levers on the left. The two on the right direct the air up (defrost) or down (heat) and the amount of heat.

Am I correct in assuming that the heater is essentially completely independent of/from the fresh air vents?

Put another way, in summer will turning on the heater fan accelerate the flow of air through the vent?

Obviously the back seat heater is irrelevant in this discussion.....
