Current sharing resistor
Those 2.2 Ohm resistors in parallel are current sensing resistors would be my guess. By measuring the voltage drop across them, or using a current sense amplifier to measure the magnitude and direction of the current, a software subsystem could infer a great deal about both the 5.35V and 3.65V were on and operating within specifications. If both were on and regulating perfectly, you would the current flowing through the resistors would be exactly (5.35 - 3.65) / 1.1. If the 5.35V supply was off or under-performing you'd get current flowing in the wrong direction through the sense resistors as the 3.65V tried to supply both loads. And so forth.
