It does not. You still have not understood that "-ciphers" constrains
**ONLY** the TLS 1.2 (and earlier) cipher lists. When you say:
ciphers ... NULL
you asking for all the ciphers (TLS 1.2 and 1.3) where the TLS 1.2 ciphers
are NULL. To also constrain the TLS 1.3 ciphers you MUST use the
-ciphersuites ...
option to list the desired TLS 1.3 ciphersuites, otherwise they remain
unconstrained.
