My teacher said when he was back in Korea, his teacher would force him to just play the correct move on the board 100 times before moving on in order to build his instinct on it. When bad moves were made, play the right one a lot just to build up your instinct and get rid of the bad move.
The problem with that method is that making the correct play (and then retracting it) alters the stimulus situation. Why? Because the original bad impulse is still inhibited by making the correct play. You have to wait a while for the bad impulse to come back in order to practice overcoming it.
I don't 100% follow. Are you saying that repeating the correct move is not fixing the root of the problem (i.e. the bad impulse)?
Particular cases may be different, but in general, yes.
One way of looking at it is this. Given position, P (or certain features of that position), the correct play is C. Thus, practicing playing C in position P strengthens the connection between P and C.
However, all this is happening in the brain, not on the go board. In the actual game, the player facing P played B, a bad play. B may have been a relatively random play, but in this discussion we are assuming that there is a pre-existing connection in the brain between P and B. We now know that this connection is not eliminated, even when the player plays C. What happens is that it is activated, and that activation is inhibited, so that the connection to C is stronger. At times, particularly under stress, the inhibition fails and the bad play is made.
The problem with the immediate repetition of C a large number of times is that the player is no longer simply playing C in position P, but playing C in that position soon after having played C in that position. The brain is not in the same state that it was in the real game, nor in the state it will be in in the next similar position in which C is correct. It is better, I am reasonably sure, to wait until the effect of playing C recently has subsided. It would be enough, I expect, to finish the review, and then to come back to the problem position. That way the move, C, will not be so fresh in the brain, and the impulse to play B will have a chance to resurface. The situation will be more like the next time the player faces a position like P, and will have to overcome the impulse to make the wrong play.

Edit: Note that this is different from the case where the player is confused and finally makes the wrong play. Then there is no bad impulse to overcome. But rapid repetition of the right play still alters the stimulus situation.
