khchen added a comment.

I think the difference between of order and unordered load is when the exception happens on memory access,
and the document said "However, using this intrinsic prevents exceptions on memory access to masked-off lanes."
IMO, it makes sense to me to assume mgather is unordered access, because intrinsic users have to set masked-off to avoid exception.
