Will "My Data" download contain chat media sent by a deleted account if it was saved in chat?

Hey everyone, I need a definitive technical answer regarding Snapchat's "My Data" export feature.
Here is the scenario:
User A sends photos (from camera roll) to User B. Both users "save" these photos inside the chat window so they don't disappear.
Later, User A loses access to the chat but fully deletes their Snapchat account (and the 30-day deactivation period passes completely).
If User B requests their "My Data" ZIP archive after User A's account is permanently deleted, will the folder chat_media actually contain the physical photo files sent by User A? Or does the permanent deletion of User A's account wipe the source media from Snapchat's servers, leaving User B's chat_media folder empty for those specific saved items?
Thanks in advance for the clarification!
