I don't think the licensing package is the final word on this. The licenses that exist on your HW 4 dongle are the only ones that will migrate to iLok when you do the one-time license migration after installing HW 5. The licensing package is a master list of all the possible sampleset licenses, but doesn't prove whether there's a HW 5 compatible install kit for the organ.
The only way to know for sure is to check each sampleset producer to see if yours have been migrated.
