قَتَلَ الْخَارِجِيَّ فُلَانٌ
So-and-so killed the rebel.
In a report about a killing, the identity of the person killed may be more relevant than the known agent. Ordering can reflect that relevance. If the listener instead asks who performed the killing, another arrangement may be better.
The objective is not to claim that every advanced dependent is exclusive, but to recognize contextual priority. Delaying one element can itself clarify the most significant information.
