Does a relative possessing two distinct blood ties inherit through both?

Primary text
A relative possessing two distinct ties of kinship inherits through both ties. This is the consensus among the deceased's family members. This is analogous to a person with two statuses, such as a spouse who is also a paternal cousin, or a paternal cousin who is also a maternal sibling; their inheritance is combined based on both roles. The calculation involves treating the double-related person as a single entity representing both kinship lines.

A narration attributed to Abu Yusuf holds that the relative inherits through only one kinship tie, but this view is not sound in itself nor soundly attributed to him.
