It would indeed be easier to flip your secondary over but it would do 
absolutely nothing (assuming you are using a standard 3-dimensional 
rotation :->   ) - the "handedness" of your coil would be unchanged.

Unless you are using a two coil setup where phasing would be 
important, I can't think of a reason that would make it important whether 
the primary and secondary are wound in the same direction or not.
