John Pattitucci Right Hand (Ring Finger) Muting

Hello, I have a rather specific question. I even made an account just to ask this. But my question is based on the use of using your ring finger on your plucking hand to mute. I first noticed Thundercat doing it, then I saw John Patitucci, then Bubby Lewis. I asked Bubby about it through his Instagram, and he said he picked it up from John Pattitucci's instructional tape, and I've been looking for the clip for a while now. Can somebody help me find the clip, or even explain it from the video themselves? Thanks for any help
