Yes, and this does offer much lower power consumption than deep sleep mode, but the current is significantly higher than what can be achieved by the GS2011M. The GS2100M can internally switch off power to the core logic. But the GS2100M module does not have a dc_dc_cntl signal, so it has no means to control an external load switch, PFET, or regulator to remove power from the on-module flash memory, the VDDIO pins, or the other power input pins. So power going to the module always stays turned on. This results in the standby current being about 50uA.
