Thread 1 corresponds to actor-topic dynamic (\ref{eq:1a}) where $B$'s late post after $A$'s \nth{1} publication does not correlate strongly enough to create the link from $A$ to $B$. But $A$'s \nth{2} post is timely enough, although not exactly on the same topic as $B$'s message, to create the tie $A \dashrightarrow B$ drawn as a dashed arrow. In thread 2, in addition to the tie $B \dashrightarrow A$, we have a topic overlap and time proximity between $C$ and $A$. This makes a the strong tie $A \to C$.
