You have the order of which are the old ones and which are replacements backwards. The "three coloured circles on a stick" are dango, that before/after is actually a mistake as the before one is the oden emoji, not the dango emoji. The smirking cat one is also a different emoji than the normal cat one, so there will be new versions of both.

Ah, thanks for the info they are different emoji and the diagram is just wrong. Was thinking the same how such a redesign could lead to misunderstandings.
