B.S he has mastered the use of them thats a fact. and they negate all chakra the only thing they do not negate is Natural energy. something that Sasuke doesn't have. the truth seeking balls do not require conscious control over them to negate Chakra. they only require concentration when you are using them in different manners like the sword of nanoboku or forming a giant armor etc etc
