WHAT IS THE DIFFERENCE OF SINGLE REVERSED VS. DOUBLE-SIDED FLAGS?

A single reverse flag is only printed on 1 side of the flag however a reverse image shows through on the other side. A double-sided flag reads correctly on both sides of the flag. It includes 2 single sided flags sewn back to back with a center liner to block the image from the reverse side from being seen.
