It either closes the box, or, if you count from the handle, downstream gear #10 gets jammed and doesn't allow the contraption to turn at all.

Those are my guesses.

It will close and open! You can not mandate it any other way!

it changes direction twice so last sprocket goes same direction as the top crank arrow?

It swaps direction 13 times (gear to gear and crossed belts produce opposite rotation). Direct belts just transfer so they're meaningless.

So an odd number of swaps - the last cog is spinning opposite of the crank so it pulls the lid up.

Hey now, I'm an engineer!!! (and yes, i designed this)
My wife is a banker, she uses this same style diagram to let me know I cannot purchase anymore fishing shenanigans.
Maybe she calls herself a banker, but is actually an engineer fucking up my good time...
