About Symmetry Plane

Hey guys,I met a problem in the case of DFBI: Lifeboat with Overset Mesh(STARCCM+ Tutorial Guide),why the Back's Boundary is set to the Symmetry Plane?

Thanks for all the friends.

it has the symmetry plane set on both the side faces of the domain and this is a cheap way to create a valid boundary in a simple tutorial like this.
in a real case like this one the side (and other) boundaries would be further way and probably set to pressure outlets with an appropriate field function
