Yes Stoff,

If you use your left hand and can stick it into the pleats then they are going in reverse direction to normal.

But, as you are going to be taking this apart anyway reversing is a fairly easy thing to do if you wish to. You don't even have to un-stitch the pleats. Just take out the interfacing if any, remove the steeking if any, and flop the inside of the pleats over.. Then re-baste and re-press.
