Aussie ATPL with multi crew only annotated on Command Instrument Rating

[A37575]

During a check of a candidate's Australian ATPL, it was noted that the page listing instrument rating showed Command Instrument Rating (multi-crew only). It may have been a NZ instrument rating automatically transferred to Australian licence?
Having never come across this before I was wondering if this a new CASA Australian licence qualification.

No such thing as a command instrument rating in NZ.

You can have a Single Pilot endorsement added if you have completed an IR test in an aircraft approved for single pilot operation.

Perhaps the multi-crew rating is current but they once held a command rating - "having held" is sufficient to fill the ATPL requirements.

Just talking it through; The common way of things over time is we all do a Single Pilot IR (Auz Command Rating) to start, then join the airlines eventually and only revalidate the IR in a multi crew situation, and thus the Single Pilot IR expires.
However, the Auz interpretation is that the person can be in Command of the Multi Crew plane you've just done the rating for (and once having met the company requirements bla bla), so any multi crew rating still gets a Command endorsement.
If you never do a Single Pilot IR, but did your initial/subsequent IR as Multi Crew, then it would be endorsed as such.
Bada Bing Bada Bang...a Command IR, Multi Crew only.
