Have a look at the schematic below ..
The top opamp is the error amplifier; the bottom opamp is the current limit circuit ..
Outputs of both are connected together (resistor+diode) to perform OR function: voltage OR current controls the output ..
By analogy in your circuit (it can be confusing, as these signals have nothing to do with the error amplifier), the outputs from current limit and thermal shutdown will be combined somewhere with the output of the error amplifier to produce a control signal to the power MOSFET ..
