It depends on where you are and what you're doing.

If you're on a pvp server, then a fear-bomb is a constant threat.
If your server is carebear, then not so much.

Aellie's sequence is for arena, so you know there's no threat until the doors open.
Even then, there's a delay before they get to you.
He would probably have a tremor sequence available to defeat fear, independent of the totem stomp macro listed.
