What distinguishes partial quotation from reporting by meaning?

The Compilation Method: Narrator Tiers, Justified Repetition and Abridgement

• Partial quotation keeps relevant original wording, whereas reporting by meaning may restate the sense in different words
• Partial quotation means citing one sentence, while reporting by meaning means using one chain
• The distinction is merely whether the full report was previously recorded
• In reporting by meaning, the integrity of contextual meaning does not arise
