It suggests that we want to actually change the cipher, and sending CCS is just a side effect. Note that all other uses of changeWriteCiphers actually change the write ciphers. If you don't want to use the other method, at least add a comment explaining why you're using it here.

Will it produce 2 ChangeCipherSpec record. One after HRR and other after SH?
