Vbat Current

I am working with a STM32F051xx for a real time clock application. Looking at the datasheet (page 53, table28: typical and maximum current consumption from the Vbat supply), it is noted below the table that the MCU is placed under these conditions: VDD = VDDA = 3.3V

My question is: do the values noted in the Vbat supply consumtion table represent the consumption when the MCU is powered on? What if the MCU is powered off? Or inversely, if these values represent the current consumption of the MCU when it's powered off, what is the current consumption of the Vbat pin when MCU is powered on?

I'd like some clarification about this plz
