I'm going to say no. Partly because it makes the power WAY too powerful if you allow it. And also because Vader and Luke really just choke people for very short amounts of time, and I could see the ones that actually kill as being more a part of the mastery's critical effect. If you allowed it to be a continuous thing, then you basically open up this scenario:
A player rolls 3 dark side on 3 dice. They use 1 to activate it, and 2 to hit 3 other targets in range. Against all four targets, they now take 3 points of wound (ignoring soak). The player then proceeds to select one of them, we'll say a Nemesis of the encounter, and succeeds in the mastery's discipline roll to perform a critical, which receives +30 on the critical roll. Now, the player commits two force dice to commit the effects. Instead of just keeping the enemies immobilized, they now continue to take 3 points of wound every turn, and the lucky enemy that has the critical, will continue to rack up criticals (which is now +40 on the 2nd turn barring any other criticals, and then +50 on the third, and so on).
And since the force dice are committed, the player who is doing all this fairly severe damage, is also free to do whatever else they want with their actions while all this is going on behind them.
This is compared to Unleash, which requires a higher force rating, more experience to really get a solid use out of it, does not ignore soak, and has its base damage be based off of Willpower.
So I'm going to say the committed dice only apply to ongoing effects like immobilize, stagger, disorient, and control's strain damage (which automatically lasts as long as any of Bind's effects anyways).
