If the tstat is set on low, only one compressor will come on.
If set on high, both compressors are powered.
HI/LO seems to make no difference on the indoor fan speed. Even though the motor for the indoor fan has two sets of windings, the real culprit is the indoor fan is controlled by the fan circuit on the tstat, and those tstats activate the same indoor fan speed irregardless of the hi lo setting.
When the 2nd compressor activates, you should notice a substantial difference in the outdoor fan.
You are not losing your mind, it took me years to figure that one out.
