Session cache (server-side) and Session Tickets (client-side) are two
different approaches to do the session resumption. Session timeout (at
least in OpenSSL) applies to both of them, but existing nginx code
(and your patch) calls SSL_CTX_set_timeout() within session cache
(server-side) code block, even though session timeout is used in
setups without session cache (server-side).
But if you disagree with my logic, then feel free to commit your
patch, you're the gatekeeper so I'm fine with that.

OpenSSL documentation is terrible and a lot of time outdated, I
wouldn't be surprised if this was written before Session Tickets
support was added.
