With Address Book, it's straight two-way wireless synchronization... where everything in one endpoint is reflected in the other endpoint.
Actually, if you log into the BES and got to the Edit Properties for the user in question. Then select PIM Sync from the list.
You will then see that most Sync fields can be changed with the following.
Synchronization Type - Bidirectional, Server to Device, Device to Server.
Conflict Resolution - Server Wins, Device Wins
You may find that the user has a change in here that is causing the issue.
