Reasoning for R44

[CrazyRussian96]

The wireless bridge power feed must be supplied by the 12VDC-to-5VDC converter (P/N: CLL25-24S05) connected to the marked 12VDC supply terminals at the end of the PD Board (i.e. the terminals located between the indicator LEDs, and not the main WAGO connectors along the sides of the PD Board) shown in Figure 4?8. No other electrical load may be connected to these terminals.

What exactly is the reasoning for the first part of rule R44 in the Game Manual? My intuition tells me that it is to prevent the D-Link from experiencing power loss due to an accidentally tripped breaker, which would cause the robot to become out of control. No amount of searching on the internet (and Chief Delphi) has yet found me a concrete answer beyond "Do this because the rule says so". Can anyone please confirm/disprove/elaborate on my idea?
