They are only used where I explicitly requested the @2x icon. Maybe I misunderstand the whole thing,  but I was under the impression that the icon at 2x.png file should be used transparently if icon.png is requested in a High DPI case.

So, I expected _both_ lower buttons to use the same icon at 2x.png, even though it's only explicitly set in one of those.

Otherwise, what would be the advantage of using @2x icons if I had to manually distinguish between high and low DPR anyway?
