Fairly sure that is not the case. If you have Sentry on, for example, any owner with the phone key would always be able to walk up to the car and push the charge cable button and release the charge cable. The reason is that the car is always awake when Sentry is on.
Or, if you open the app and wake up your car before approaching it, you can also remove the charge cable with the cable button.
It’s possible that removing the charge cable also unlocks the car (no idea), but I am fairly sure that prior to pushing that cable button, the car is locked.
The requirement is that the car is not asleep.
