The two tasks that are in the Suspended state prior to calling vTaskSuspendAll() will remain in the Suspended state after xTaskResumeAll() is called.
The function name is a little misleading, which is why, as part of the code review, the functions vTaskSuspendAll() and xTaskResumeAll() were renamed vTaskSuspendScheduler() and xTaskResumeScheduler() respectively for the SafeRTOS code.
