Can you play expeditious retreat to escape from your own combat?

[Munchiess]

Question in title.

The card says the following:

If you are helping in combat, play
this to remove yourself from the
combat without penalty. The main
player may ask for another helper
.
Or play before rolling to Run Away
to escape from all monsters in the
combat automatically. (You still
cannot escape from monsters that
automatically catch you.)

[Brf]

The second paragraph does not stipulate you must be a helper, so I assume you could use it to escape from your own losing combat.
