Hi Brian, yeah there could possibly be some situation (particularly if you have kind of sparsely distributed sections all at different angles to one another), where the automatic orientation might not be correct, so that's why you are able to adjust it manually so there's some way to fix it if it didn't do it properly.

Basically clicking on one section will reverse the direction of that curve in the loft.

Also at that same stage if you look in the viewport you should also see 2 points in there as well, those are marking the "seam" locations of where the closed curves will connect up to one another, you can click down and drag the mouse on one of those points to adjust the seam location, either to fix it if the auto untwister did not do a proper job, or also you can introduce twist by changing that seam location as well.

Usually there should not be any need to mess with those adjustments since usually the automatic "twist minimization" is pretty good.
