A common cross-linguistic grammatical process involves repetition. This generally operates at the morphological level, as reduplication, and can carry any of a variety of meanings. In Jarawara repetition operates at the syntactic level. After a fully articulated main clause, can be added a truncated version of it (including just the core components). This has purely semantic effect, indicating that the activity referred to is extended in time. The "summarizing clause" in Jarawara looks a little like "bridging constructions" (also known as "head-tail" or "tail-head" linkage), but it is functionally quite different, playing no role in establishing discourse continuity.
