No, because the plaintext is symmetric-encrypted with a random session key on the host. The smartcard just asymmetric-encrypts the session key. This two step process is used mainly because asymmetric encryption is comparatively slow, but it also means that two identical plain texts won't get encrypted to the same ciphertext, due to the random session key.
