Yes. But a threshold is NOT the same as 'you're basically buying 1 hit per die'. Because if it involved dice, it'd be an opposed test and you wouldn't be rolling a single attribute to resist. So it's NOT equivalent to an opposed Strength roll, because it's not an opposed Strength roll. It's Close Combat + Agility [Opponent Strength]. If it were an opposed roll, it'd still not be an opposed Strength roll, it would be Close Combat + Agility vs X + Strength, where X likely would be Body, given similar pools. So RAW this is NOT an opposed Strength roll, and even under a different rule it wouldn't be.
Also, Disarm is NOT 2 attacks. You Call a Shot, spend 5 Edge to make it a Disarm attempt instead, then roll the normal attack. Not sure why someone told you different.
