I assume by "trigger" he means what it means (from what I remember) in
some other packet analyzers, namely a Boolean expression that tests the
contents of packets, and that causes packets to start to be saved when a
packet for which the expression is true is seen.

That would be used in a case where "interesting" traffic is defined as
"traffic following a packet of a particular type".
