Does the T2 Tempest core enhancement work with handwraps or are they not considered dual wielding?

"Tempest: You gain +10% chance to make off-hand attacks when dual wielding. While you are dual wielding, you can use your dexterity modifier to hit with light melee weapons. You now treat Scimitars as if they were light melee weapons."

Obviously Shintao Deft Strikes does work, but I'm not seeing any (Effects) feedback when I toggle between wraps and two kamas that indicate the Tempest ability is actually functioning.

Any idea?
