Exactly.

If it worked at all, which I don't think it would.
Actually the "gorging on honey" theory was in Langstroth's books and is generally accepted, but my guess is that smoke works more by interfering with their sense of smell which keeps the alarm from getting raised. I open a lot of hives with no smoke because I'm looking for queens and find just as many bees gorging on honey as when I use smoke.
