STM32U5 Serial Bootloader AN3155 Discrepancy

In looking at AN3155, USART protocol used in the STM32 bootloader, the following diagram describes the MCU's write protect command sequence from the device side:

There is a comment at the bottom which indicates that only certain F and L series chips perform the system reset.  I am working with a STM32U585QI, and I also see that this chip appears to perform a system reset when executing the write protect command.  Is that correct and this comment is just wrong, or am I seeing this unexpectedly?
