That's due to the Mailman filter in above reference.
The Mailman filter uses the SYMBOLS spamd method, rather than PROCESS,
which makes spamd return the status, score and a list of rules hit only.
Unlike with PROCESS, the message itself is not returned, thus no X-Spam
headers either.
A closer look at the python code suggests, the filter even hardly cares
about the rules hit -- it just cares about the score to decide whether
to pass, moderate or discard the message. That decision is passed back
to the Mailman filter chain.

Generally, the client (a mailman filter in your case) passes the message
to spamd, which after processing returns the modified message. As you
pointed out correctly, this modification by default adds some X-Spam
headers, at the very least an X-Spam-Version header.
The docs you cited apply to SpamAssassin. The method the Mailman filter
uses is spamd specific, though, a daemon implementation using SA at its
core.
There's also a general misunderstanding here. While the client passes
the message (a copy of the message, rather), it is up to the client what
it does with the returned data -- including outright ignoring the result
with the X-Spam headers added, and proceeding with (a copy of) the
original message.
In order to have the added X-Spam headers show up later, the client has
to discard the original copy, and pass along the modified version as
received from the daemon.
If you want the X-Spam headers, you will need a different Mailman
filter / documentation to follow.
