Presumably the %uni_refs hash's values correspond to indices that should exist within @allrefs. So the values are sorted in ascending order forming a list of indices desired. Then they are used to take a slice of @allrefs, in that order.

Seems like a pretty useful way to grab the wanted elements in a desired order, allowing for duplicates and skips as needed.
