SecuritySuite - SuiteCRM and CE Teams

I'm using SuiteCRM and their custom sales modules (i.e. quotes, contracts, invoices...) are not related to SecuritySuite. If I use the "Hookup Module" functionality to relate them (funny enough, it fails the first time and succeeds the 2nd attempt), the values in the "securitygroups_records" table seem to be reversed i.e. "securitygroup_id" field contains the related record id, the "record_id" field contains the security group id and the "module" field contains "SecurityGroups" instead of "Quotes" for example. Is this by design? I ask because if it is, how do you know which table that related record comes from?
