[AnimNotifyState]Interupt montage with the same montage ANS Received_Notify call in strange

Add an AnimNotifyState on a montage. Play the montage and interupt it with the same montage when it is in the AnimNotifyState. 2 pairs of [Received_NotifyBegin and Received_NotifyEnd] are called in a short time. Counting in start-end totally there are 3 pairs calls which is strange.
When using two different montages, both added the same AnimNotifyState, the result is totally 2 pairs of calls which is easy to understand.
