Is behavioral targeting misbehaving?

DMNews reports that Wal-Mart is working with Yahoo to incorporate behavioral targeting into Wal-Mart’s web site.

For example, when a shop­per puts a digital camera into a shopping cart and then takes it out, Walmart.com will be able to deliver an ad for a digital camera the next time that shopper returns to the site.

Does this seem a little counter-intuitive. If these actions were an actual conversation, wouldn’t it sound like this?

Consumer: (camera into cart) Maybe I’ll get this digital camera. Nah, this isn’t the time. Instead I should change my oil and redo the house with energy efficient bulbs. (camera out of cart.)

Wal-mart: Hey! How about this awesome digital camera! It’s shiny!

I understand an attempt to steer ambivalence back to a sale, but cranky or fiercely independent souls might feel that the website is arguing with the customer’s intent in this example.
