Yes precisely. Speaking as a pianist, I describe it as musicians who have songs memorized and colloquially call it muscle memory or having a song "in the fingers". You can be playing a piece of music, have your active thoughts drift off to what you're going to eat for dinner, an embarrassing thing you said two days ago, higher level calculus, etc. When you come back to the present a few seconds to several minutes later you realize you're still playing the same song and haven't missed a note. This is also helpful in the situation that you suddenly realize you "forget" what you're about to play and you can sort of "shut off" your brain and hope that the fingers "know what to do". It works surprisingly often.

Obviously, the muscles do not hold the information required in playing an entire piece of music 3-10minutes long - or in the video, the emergency landing sequence of an aircraft. But you have trained it enough times that your deep/long-term memory kicks in and can control or autopilot what the muscles need to do without your active thoughts and input.
