As I explain to people all the time, if you are walking along holding a little flag on a stick, the blue field faces the front, with the stripes dangling towards the back (unless the wind is coming from behind you). The little flag on the right shoulder has the blue field towards the front--so it is oriented the same way as the little flag on a stick.
The other question people used to ask is, "What does An Army of One mean?" Thank goodness we don't have that slogan any more; I never could answer that one.
So it is symbolic of walking forward instead of being displayed correctly?
Okay... kind of stupid... but, okay
