19.22% - owned by ISX or Nick Karantzis?

In the ISX 30th June 2020 half yearly report it states that:
"The Company in the same period invested $5.7m cash to acquire 19.22% of the NSX Limitedand received $3.2m for the NSX investment in ClearPay Pty Ltd, such that normalised cashat bank without this investment would have increased to $18m".
NSX company research states that Nickolas John Karantzis has a shareholding of 19.22% in NSX.
It does not state that ISX holds any shareholding whatsoever in NSX.
I may have misunderstood the posters here on ISX but it seems to me that they are under the impression that ISX own part of NSX.
As I see it, only Nick Karantzis will enjoy any financial benefit generated by NSX.
There are a few excellent posters on this forum and I would be grateful if someone would explain this discrepancy to me.
