That should not matter. As a matter of fact when I am cutting a rear axle that is not threade all the way, I take the cut on the left side, leaving the freehub/freewheel side with the most threads. A way to make sure you have enough is to take out the axle leaving Right set of nuts,cones and spacers on the axle. Hold up the solid axle to the QR axle and do a visual check. I think you will find there are plenty of threads to make a single cut.
