Just now I lost my Contact list while syncing from my iPhone to Address Book on my Mac.

Details:

My master Contact list lives on Mac A. I sync it regularly to my iPhone. Once in a while I like to copy the whole contact list to Mac B. Here's how I do it:
  1. I open Address Book on Mac B and delete all contacts.
  2. I connect my iPhone to Mac B.
  3. iTunes opens.
  4. In iTunes I go to Devices -> iPhone -> Info and click the "Sync Address Book Contacts" checkbox (All contacts).
  5. I click Apply.
  6. iTunes gives me a confirmation prompt because syncing would affect a large percentage of my contacts. It asks me which way I want to sync.
  7. I click the choice to sync from the iPhone to the Mac.
  8. It does the sync and I end up with the contact list on both.
This has worked fine the several times I've done it.

Today when I tried this, however, I didn't get the prompt in Step 6. It erased all contacts on the iPhone without comment, leaving Mac B's Address Book empty and the iPhone empty as well. Yes it left them synced, but not the way I wanted.

Why didn't it ask?

I still have my master Address Book on Mac A so I can the list back on my iPhone (I could also restore the iPhone from the last backup) but this is highly annoying and I don't know what made iTunes behave differently this time. I could use other methods to sync, such as saving from Mac A and restoring on Mac B, or syncing through a MobileMe account, but this way has been the most convenient and I'd like to be able to use it.

Any guesses as to what prevented iTunes from asking its usual question?
