Hi there, R2 feeds some current from +9V to the +5V rail. This won't change the voltage as long as the consumption on +5V is always higher than the current through R2 (200 mA or a bit more as +9V is usually a bit higher than nominal 9V AFAIR). Probably the consumption on +5V is too high for the regulator on that rail so Commodore tried to mitigate that problem. The note reads that this is needed for french devices. I think I have read somewhere that the french version of the C64 had a special board to transcode the PAL video signal to SECAM as used in france. That board might increase the power consumption.
