It doesn't mean much. Some, including myself, don't like under-seat mounted bags, with Velcro straps that go around the post, for the same reason. Bigger thighs = bib abrasion.
If your saddle works for you, don't change it for this. If the position works for you, don't change it for this. Saddle rail widths are standard, so there's no changing that...
All that said, you've got a post with very little setback and your saddle is clamped at the very front of the usable rail range. You could go to a ~25mm offset post and clamp further back on the rails while maintaining the same saddle position. Putting the clamp a little further back, and under a wider portion of the saddle, might give you just enough to avoid rubbing... No guarantees, though.
