Summary:
If you move a message to a particular mailbox, the Message menu contains the proper "Move to xxx Again" item. If you then COPY a message to that SAME mailbox, the Message menu item does NOT get updated to be "Copy to xxx Again" but instead remains "Move to xxx Again". The same is true in reverse (copy and then move).
Status:
Apple knows about this issue and is working on it (Bug ID# 4016204).
