Hi Adrienne - each register refers to the restriction and Option to purchase as per the terms of the 2018 Transfer. The clauses you refer to state that is what had to be done, and both were then registered on application and I assume that's what you mean by compliance.
If you mean whether any subsequent Transfer or other disposition complied with the restriction then whilst you can assume that they did, as each was registered, or you can apply for an official copy of the certificates provided on each subsequent application.
There's no compliance linked to an option to purchase other than the persons with the benefit of the option then exercising it as appropriate.
