However if I subsequently edit the new book and do another wireless sync the file name is changed to use the new ID so it is all then synced correctly.
Calibre use internal metadata for matching, not the file name. Note ID can be different if you have different Calibre installs (different computers), because ADD uses the next available ID. So if you add books to different systems, transfe (eg copy to Library), the ID will end up different between systems.
I ended up dropping {ID} from the file name a bunch of years ago for thos reasons.
