Because you are connecting the signal after the volume control well sort of. The vc doesn't have a lot of impact on the ant side of things till it is at a pretty low resistance (shorting the signal to gnd) On the cathode side the vc has much more affect by varying the gain of the rf amp tubes.
So the vc doesn't do much till it's all the down affecting the signal coming from the ant but you are bypassing that part of the vc. The vc will work some because it still can control the rf amps gain though the cathodes. If there wasn't a connection from the vc to the ant when you turned the set all the way down you would still hear some signals. With it hooked to the ant it eliminates this situation
Clear as mud right???

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
