Sure, I also use finger replacement, and use all possible physical clues (nut, neck heel, continuous contact with the neck, etc.) as much as I can when I play.I use finger replacement to find my first note on upright. For instance to play C# on the G string, I can reliably find 4th position (D) with my 1st finger, replace it with my 2nd and the C# is just there. With bass guitar, I have to look. I don't have the same guideposts.
Yet, what I wanted to demonstrate the simple exercise is that, even without any starting reference (hence the step where the arm is droped so that the hand is not at all in contact with the neck before finding the note), muscle memory can learn (and actually learn quite rapidly) how to play in tune a given note on the neck.
With the additional help of physical cues, one can do even better.
