Information conflict with SEAL regarding size of ciphertext under different key mode

[ZiyueXu77]

Question

According to benchmark tutorial: "the symmetric/asymmetric encryption switch doesn't actually impact the size of the ciphertext, only of the context", but according to SEAL (https://github.com/microsoft/SEAL/blob/main/native/examples/7_serialization.cpp) "ciphertexts can be created in a seeded state in secret-key mode, providing a huge reduction in the data size upon serialization". I wonder if I have some misunderstanding? Or there are some deep reason for this descrepancy.
