Conductive weapon properties and Chill touch---help?

[Taijutsu]

I'm building a recurring villain inquisitor for my game who uses a conductive sword to use some nasty abilities. For most of his spell-like abilities it's very clear how this works. He hits somebody with the sword, and once per round can expend two charges of that ability and WHAM! One Touch of Chaos/Laughing Touch in your face! However, I'm having trouble with one of his spell-like abilities, chill touch, which he gets as a racial spell-like ability.

Chill touch explicitly states that the caster of the spell can use the melee touch attack once per level. This dude is currently 6th level, so if he were to use this spell-like ability normally, he could zap someone 6 times after activating it.

The Conductive property states

:

A conductive weapon is able to channel the energy of a spell-like or supernatural ability that relies on a melee or ranged touch attack to hit its target (such as from a cleric's domain granted power, sorcerer's bloodline power, oracle's mystery revelation, or wizard's arcane school power). When the wielder makes a successful attack of the appropriate type, he may choose to expend two uses of his magical ability to channel it through the weapon to the struck opponent, who takes the effects of the weapon attack and the special ability. (If the wielder has unlimited uses of a special ability, he may channel through the weapon every round.) For example, a paladin who strikes an undead opponent with her conductive greatsword can expend two uses of lay on hands ability (a supernatural melee touch attack) to deal greatsword damage and damage from one use of her lay on hands. This weapon property can only be used once per round, and only works with magical abilities of the same type as the weapon (melee or ranged).

If he were to attack with his sword and conduct chill touch, would it:
1. Use up two of his per day uses of the Spell-like ability Chill
Touch.
2. Use up two of the 6 zaps per activation of the Spell-like
ability Chill Touch?

My main problem here is the ambiguity of the word "uses" in the Conductive Property and how "channeling" the ability does not state whether the effect of the ability is transferred through the sword strike or if the ability itself is activated through the sword strike.

What say ye?

Probably GM fiat at this point. I would say uses up two rounds.
