Oh, no question it is line of sight. But I will counter that in those regions that are "around the corner" electrolysis still occurs, but just not as fast. There may even be a point in the "back corner" where electrolysis doesn't occur fast enough to counter the forward oxidation of iron. And there may be some point or line in the bath where the two forces, oxidation and electro re-composition, just about match.

Another good reason to use Prep & Etch after removing items from the bath. It kind of the extra "shove" that puts iron into that desireable Fe304 oxidation state. Or it's phosphated equivalent. (see reaction above.)
