This sysctl allows a deeper dive into the sleep abyss comparing to debug.acpi.suspend_bounce. When the new sysctl is set the system will execute the suspend sequence up to the call to AcpiEnterSleepState(). That includes saving processor contexts and parking APs. Then, instead of actually entering the sleep state, the BSP will call resumectx() to emulate the wakeup. The APs should get restarted by the sequence of Init and Startup IPIs that BSP sends to them.
