In fact there is a difference which can come in useful. I've learned something.
It all depends on how someone chooses to interpret your question.
You asked if there is a difference in 10.11.5. That can be interpreted as,
1) Has Arrange and Sort changed in 10.11.5 from what it has been since Mavericks (I think).
2) What is the difference between Arrange and Sort (introduced several OS's ago).
A better title for the post would have been, "What's the difference between Arrange and Sort?"
That makes it clear what you meant and people won't wonder if you are experiencing a different behavior in the specific version, 10.11.5, than you have seen in previous versions that implemented Arrange and Sort.
