You don't have the picture.
metadata.opf gets rewritten any time ANY of the data for that record in the DB changes. It is a Backup. Sometimes other activities trigger a rewrite.
Adding /removing a Column, making a change to a TAG that was also USED in that book. Obviously, you triggered a update on 20 Jan (btw there is a button item under maintenance:backup status, that forces a update)
It does not matter WHEN you downloaded a HOG of a comment. It is there until you open the MDE and PRUNE it (or delete the book)
