Not exactly how it works, steganography can produce a plaintext, picture or whatever as a cover for the ciphertext, but the cover is not going to be identical to the original. Consequently steganalysis will be able to recover the ciphertext. But with deniable steganography you can use a fake key to decrypt the ciphertext, so the guy standing behind you with a $5 wrench can see that you have nothing to hide.
