Well, the returned value leaks all the bits of information, unless that is randomized too to prevent replay attacks.

In homomorphic systems the server only sees the encrypted result. Since it can not decrypt it, it doesn't gain any information from it. And indeed the encryption is scrambled differently for each query, otherwise you could learn if two values are the same.
