The Menorah that was commanded to be made in the Bible and which was lit in the Tabernacle and the Temple had seven branches....A "Hanukkiah" (Chanukah menorah) has nine branches for the eight days of the holiday (and one candle used for lighting the others)

The author is a religion columnist and Professor of Religion. He mus know the difference, think it occured to him?

Most people don't pay attention to these little details. ;)

The State of Israel uses the 7-branched Menorah in its official seal.

The 9-branched Menorah is used specifically for the Chanukah observance.
