It depends.
If you ever want to use an index in descending order, you can always use
SET ORDER TO myindex DESCENDINGso there isn't a reason to create the index descending.
However, if the usage of this index is almost always in descending order, then you might as well create the index that way.
Insanity: Doing the same thing over and over and expecting different results.
