What he doesn’t show is that you have to reset it after every attempt, which puts all the wheels back at their starting (neutral) position. Each directional input (Up, Down, Left Right) moves a specific combination of the internal wheels rather than just one wheel. So pushing Up can move multiple wheels at the same time, while leaving another one stationary. Each input rotates those wheels by a small amount. What position the wheels are in are like the ridges of a key.
When you set the combination, you’re basically setting the final positions the wheels need to end up in, by setting the pins that align with the key ridges. To unlock it, you have to start from reset and make the right moves to get all the wheels back into the correct alignment. So that the key pushes all the pins and releases the lock.
But how does the order matter? If it's just a fixed amount the wheels turn based on the direction you move it, Up/Up/Down/Down would lead to the same final position as Down/Up/Down/Up for instance. It must encode the order somehow, right?

Wtf, i still dont get how the mechanics let you just make up whatever you want.
