On Block Diagram which BUS connects to the RCC

On the STM32F407VG data sheet, I do not understand the block diagram (shown below) with regards to the RCC. What BUS does the RCC connect to?

On Table 1 (shown below) in the reference manual for the STM32F407 DISCOVERY board it looks like the RCC is connected to the AHB1 BUS based on the register boundary. Is this just an error on the Block Diagram not showing the connection? Or am I missing something?

Top level AHB, not sure why this is consequential. 

Always enabled and clocked.

As @Tesla DeLorean says, why is it important?
