I don't think the theory is that the muscle memory sequences resemble each other.

Instead, it's that because muscle memory allows you to do things without thinking about it, you can get mixed up about which action you meant to perform and go through the whole process without realizing it.

Is actuating the fuel cutoff switches something that is done routinely in these aircraft, to the extent it could reasonably become muscle memory?

ETA: downthread it is mentioned that these switches are used on the ground to cut the engines

Seems akin to something like a parking brake. Something you only use at a stop, or rarely during an emergency.

They're pilots, they do hundreds of stops each year. In case of domestic pilots, even thousands. And with years of experience, switching off fuel control switches is basically muscle memory at this time now.

Was amused to see they have one of those too, with "parking brake" written on it.
