Counterintuitively, sequentially applying additional crypto doesn't necessarily improve security; in theory, it may actually damage it.

  Any pointer to explanation of the phenomenon?

  If the keys used for each cipher are independent it should not weaken security. See section 15.7 of Applied Cryptography (http://www.cse.iitk.ac.in/users/anuag/crypto.pdf http://www.cse.iitk.ac.in/users/anuag/crypto.pdf).
