The documentation for Expression.reverse_ordering says it is its own
inverse:
https://docs.djangoproject.com/en/1.11/ref/models/expressions/#django.db.models.Expression.reverse_ordering
> Returns self with any modifications required to reverse the sort order
within an order_by call. As an example, an expression implementing NULLS
LAST would change its value to be NULLS FIRST. Modifications are only
required for expressions that implement sort order like OrderBy. This
method is called when reverse() is called on a queryset.
However, this isn't implemented.
