Yes, the gearbox is effectively locked, but I am a little confused by “while the clutch is disengaged”
The Auto Hold, and parking brake are two separately operated system. I love auto hold, it is one of the many advantages of an automatic, it simply applies when your braking and the car comes to a standstill, releases when you operate the throttle. Hence your brake lights are on, as the brakes are applied.
When the parking brake is applied, the system engages just the rear disc brakes. Some manufacturers used to have a separate, small, drum and shoe system, within the rear brake disc for the handbrake/parking brake, but many done away with that when I was in the motor trade……..and that was decades ago!

Does anyone still drive a manual car? LOL! Obviously I was referring to an automatic gearbox as I have never come across any manual gearbox where you can select Park, but happy to be corrected?

My Toyota removes Autohold after about 5 minutes and applies parking brake. Rear brake lights then go off. Not dissimilar to yours.

The 2014 Santa Fe has the hand brake / electric handbrake , operating on cables to brake shoes, operating inside a drum on the rear discs.
This morning I have just received a recall on the Hydraulic Electronic Control Unit, for a fuse rework.

Looking at my neighbours Captur a 24 registration the rear has drums which I assume have shoes inside them.
So ten years old now, some manufacturers phased that system out decades ago…..You live and learn. I have not worked on vehicle brake systems for around d 30 years.
Yes Clive , it isn’t unusual for a smaller, lighter car to still have drum brakes, at least the wheels don’t get covered in that awful brake dust! The front brakes do the majority of the “stopping” the rear brakes help the car keep in a straight line.
Having said that, the tow cars we need, larger cars that need to tow at the very least 1.1t will, or will preferably have disc brakes all round. 👍

And you still adjust the handbrake shoes through a hole in the disc drum. Old tech, but easy, unlike the handbrake module to operate the cables.

I could have worded it better: When in the "Park" position the clutch is disengaged (which allows the engine to be started etc), but at the same time the gear box is mechanically locked so the output drive shafts cannot be rotated.

The SF , Sorento and many others use discs all round with built in brake drums and shoes for the handbrake only
A broken gearbox would be the least of my concerns if I got rear ended , when THO got rear ended whilst broken down it was three weeks in a coma after removal of a subdural hematoma, car declared a write off ( it started out as a corsa and ended up as a nova!!)
If it ain't broke, don't fix it - drum brakes work just fine for parking brakes, they don't get hot in use so don't need the better heat dissipation of disc brakes.
But using the rear disc brake as the parking brake is old technology in itself - my 1967 Fiat 124 had a parking brake that operated on the underside of the rear disc brake piston within the caliper.

With the old Landrovers the handbrake clamped onto the half shaft. Replacing half shafts was good for business!
And when you pulled on the hand brake while still moving it was a case of “Everyone down the front!!!😆😆

Most certainly did Roger, other manufacturers, especially Italian, adopted the same. It was an absolute nightmare!

Just clocked up 98k miles in my SantaFe, the handbrake shoes are fine. But mostly longish journeys.
