Does the SYS_RESET pin in the Jetson Nano physically cut power to the board?

As the title says. I wanted to know whether or not the SYS_RESET triggers the Jetson Nano to cut power to the board in order to reset, or if it is some software magic happening behind the scenes.

I checked the product design guide and the only info it has is a mysterious connection to the power subsystem within the nano, but nothing else. The datasheet is just as helpful unfortunately.

It is a signal from/to PMIC in the module to run a reset process.
