Yeah, I would like to see the reactions written out for each stage, maybe then I could understand it.
Thinking about how electrolysis for rust removal works, the rusty piece is put on the negative wire and the rust is reduced and the ions transported to the positive side. But that usually has a base for the electrolyte not an acid.
In this case, maybe the stainless bar in the first reaction was sending chrome to the spoon, then in the next reaction it was reversed to plate the target. I may have to dig out an old textbook and do some studying again.
