I'm no engineer but what I heard is that besides the signature design which I love, it actually has functionality. If I remember correctly, it has something to do with reducing back flow of air to make the air flow better and also has positive impact to the sound a little bit.
Imagine turning a bottle full of water upside down to let water go but with a chopstick sticking out.
