This goes well beyond my very limited knowledge so I did an
experiment.  I went to the gmail web interface and found an
already-opened message in the All Mail folder (really a label)
that I knew for certain I had originally opened in gnus, so
therefore gnus would have known about the message.  I marked
it unread (on the web) and moved it back to INBOX.

Then I started up gnus and gnus saw the message as an unread
INBOX message.  Based on this it appears the answer is yes,
gnus did update the status of this previously seen email.
However I don't know how much if any status information gnus
actually keeps (and I don't use the registry) so this may or
may not be meaningless.  It certainly seems as if, when
reopening the group subsequent to shutting down gnus at some
point, gnus gets a fresh set of information.
