Jose,

There are two reasons. To get a good back rejection you need to screen
off sounds from the rear. The other reason comes from the theory of
how a horn works, The back end or "throat" is a high pressure area
which is why you get amplification. If this sound pressure can leak
past the mic, it will not give the best gain. With brass musical
instruments this works the other way around, but you have to keep your
lips sealed against the mouthpiece.
