Switching RE1 and RE2 affects the biasing and feedback network of the amplifier. RE1 typically provides bias stability and affects input resistance, while RE2 (if part of an emitter degeneration configuration) affects gain. Swapping them would likely increase the input resistance due to the change in biasing network configuration but decrease the gain because the feedback through the emitter (which stabilizes the gain) would be altered.
