Boot configuration for STM32G071

For STM32G071 controller, I see difference in information provided in Ref manual (RM0444 Rev4) and STM32 microcontroller system memory boot mode applicate note(AN2606 Rev44).

1. In Ref manual on Pg 60 section 2.5 it is mentioned that for selecting boot from system memory we’ve 2 options.
2. Option Byte from Ref Manual, pg no 73 section 3.4.1 says that all nBOOT0, nBOOT1, nBOOT_SEL bits are 1
3. so any of the option to select system memory boot will not work unless I change the option byte value in user application or using tools like STCubeProgrammer or DFuseDemo
4. In Application note(AN2606), on pg no 206 section 40.1 it is mentioned to refer pattern 11 from table 2 for STM32G07 controllers.
5. Pattern 11 from table 2 pg no 24 section 4.1, 2nd option does not check nBOOT0 bit in option byte. So this option does not require any change in option byte as rest fields nBoot1 and nBOOT0_SEL bits are already set to 1 as in default value.

My questions:

1. Is there error in documentation wherein this difference is just an error?
2. If there is error in documentation, can I get correct document?
3. If Application note(AN2606) is correct then can I enable boot from system memory? 

Thanks,
