NSW 2005 Norton Utilities: Does undelete *require* it be deleted *while* protected by norton?

I've never quite understood this, and my searches within this forum aren't getting me anywhere.

 

Does the NU 2005 undelete mechanism require that the file be deleted *while* the recycle bin is protected by norton?

 

I seem to remember an undelete that allowed searching the unused surface of the HD looking for (un-wiped) deleted files.  Currently I'm resorting to other utilities (Glary) for this.
