Thank you for your query.
1 resultId will only have 1 referenceId.
referenceId is the profileId and contains the full information for the specific match/profile. Whereas the resultId is used for resolving the specific match in a case.
In order to fetch the full profile information of a match, you may use the API call - 'SEQ-case-investigate-world-check-profile: Get a World-Check profile' and pass the referenceId.
Hope this clairfies your concern.
