Addresses are not secret. Printing the name with the address might seem like a privacy faux pas, but in actuality it's a mailing faux pas. If USPS knows you don't live there anymore, they return to sender. That's a lot of expensive postcards going around for nothing. If however, it is addressed to "current resident" it's not a problem.

The story seems like trying to make lemons into lemonade. "Well, we wasted money, but maybe we can get a bit of privacy protecting glow from this cock-up anyway."
