Probably, what's in the Cc: header in all cases is something like
Real Name
or maybe just
r...@example.com
How this is displayed by the email program reading the mail is a
function of that program (Outlook or whatever).

When from_is_list = Munge From, the original From: header is replaced by
From: user_name via list_name
and the original From: is placed in Reply-To: or since Mailman 2.1.19,
if reply_goes_to_list = This list, in Cc: to expose the original
sender's address and facilitate replying to that address.
I suspect the difference in this user's case is that for her posts, here
original From: header has just her email address rather than her name
and address, so just the bare email address gets put in Cc:
Also note, that from_is_list = Munge From is currently deprecated in
favor of from_is_list = No, and Privacy options... -> Sender filters ->
dmarc_moderation_action = Munge From.
This will apply DMARC mitigations only to those mesages From: a domain
that publishes a DMARC p=reject (or quarantine) policy.
