To spell it out more explicitly, this change appears to be incorrect.

3.6.6. Resent fields

Resent fields SHOULD be added to any message that is reintroduced by a
user into the transport system. [...] No other fields in the message are
changed when resent fields are added.
[...]
resent-msg-id   =       "Resent-Message-ID:" msg-id CRLF
[...]
Resent fields are used to identify a message as having been reintroduced
into the transport system by a user. The purpose of using resent fields
is to have the message appear to the final recipient as if it were sent
directly by the original sender, with all of the original fields
remaining the same.
[...]
Note: Reintroducing a message into the transport system and using
resent fields is a different operation from "forwarding".
[...]
Note: When replying to a resent message, replies behave just as they
would with any other message, using the original "From:",
"Reply-To:", "Message-ID:", and other fields.
[...]
The "Resent-Message-ID:" field provides a unique identifier for the
resent message.
