Example of discussion representation

I just wanted to confirm (or not) my understanding of using AS to represent a typical discussion on a social network.

I (randomly) found this Yammer discussion example: http://www.iimedia.cn/cover/1340788676364l25il.png


If we wanted to just represent the first discussion, is the best option to use a Story with a Note for the first post (by Alissa)
which would have two other Notes (Ryan and Michael) that would be attributed as “inReplyTo” to the first Note?
