However, if you take a moment to analyze it, it seems that it allows for excess water pressure from the high-side of the radiator (driver side) to dissipate into the low-side (passenger side) of the radiator in situations during high-revs.

Another, more simpler reason would be to allow air pockets/bubbles to escape from the high-side to the radiator neck on the low-side.
yan din isa sa naisip ko, last ko naisip ay baka ito yun dapat para sa supposedly heater, kaso wala naman need ng heater sa atin and para makatipid imbis na radiator design ang i-alter ay i-rekta nalang back sa radiator hose? di kasi kita, but that side tube from radiator cap, is actually 2mm (+/-) larger than the one exiting to the reservoir. makes sense ba?
