It seems that this is not included in this PR:

Support binding one animation to multiple statuses

Although it helps code reuse, it increases the cost of understanding, so I tend not to support this feature.

@xushiwei Do you mean "Support binding one animation to multiple statuses"? If you prefer to limit that one animation can be bound to at most one status, what if the user want to use the same animation for two differnt statuses? We recommend him to create two animations with the same data?
