My understanding is that SFG have a few different contracts on Legune. One is a long term lease for the PSD site, another is a water-use agreement and a third - and perhaps the one most relevant to your question is an option to buy Legune - that option would have been written with an “or nominee” clause, allowing SFG to nominate AAMIG as the purchaser when that option is exercise- the land will only be transferred once - from Legune’s current owners to SFG’s nominee.

Nominee clauses are fairly common in real estate transactions.
