(Twindance only works in Melee range, unless shuriken)

I will say this is not correct, ranged weapons that can twin dance (All guns) work at maximum range, as well as Chakram fist weapons, also any dagger with throwing knives skill.

Edit: In fact, there is an interesting interaction where if you twin dance a Rifle or Jackhammer, with an offhand pistol or shotgun, they will both still attack, even outside of the handgun/shotgun attack range.

Yea, the tooltip is very misleading atm.
