Symmetrical doesn't mean that every element is symmetrical in itself.  
For example, humans (and all animals with backbones) are considered 
bilaterally symmetrical.  That means the right have is basically just 
like the left half.  Not that the top half and bottom half are the 
same, and not that the front half of the right ear is the same as the 
back half of it.

I suspect they put the word "symmetrical" in so people don't submit an 
edging and say it's a table ribbon.  If you did Beds or Floral Bucks or 
any edging pattern down and back again (like an edging that was folded 
and sewn, sewing-edge to sewing-edge), that would be symmetrical.  
You'd have to design something for the ends, though.
