Turns out you can lock the car (with remote or touch door handle) with the boot/trunk/luggage compartment open, the car locks.
The dash led shows door open but the car still locks instead of beeping as it would if you left the driver or passenger door open.
The trap here (apart from the car not being totally locked) is that the boot/trunk/luggage compartment lamp will drain the battery.
With the boot lamp 5W and the dash indicator, there is 760mA drain (8.8W), this will totally drain the battery in 48 hours.
Car Armed (driver and passenger doors closed, boot/trunk/luggage compartment open).
