There are two cases:

1. Should we update the statistics when "and-chain" ends?
2. Should we deliver the notification when "and-chain" ends?

For the first one, I think we should update the statistics when "and-chain" ends
because it makes statistics more accurate. For the second one, maybe I misunderstand
the "and-chain", tested it aggin and find the notifications will not deliver if
the last transaction is aborted.
