Perplexed by '64 Thrift Air Push/Pull Knob - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I took out, lubed up, and reinstalled the Thrift Air cable in my '64 C10 today and what a world of difference.

Now that I can pull the knob out all the way, I feel a greater amount of air coming through the vents, when pushed in, it's like closing a damper and the air flow greatly decreases. If I can adjust the heater's air flow with the fan's 3 speeds, then what's the purpose of pushing and pulling the knob, or am I missing something?
