Airxcel Thermostat - Cool Auto settings?

Feels like a dumb question but I've never seen this in residential!
The thermostat has the usual Hot - Cold - Fan, hi and low settings as expected...
What's the difference between Cool Hi and Cool Hi Auto? The manual only shows the options, but no description of the difference.

Thanks!

Auto (either high or low) means the fan cycles on and off as required. Hi/low (non-auto) leaves the fan running all the time and just the compressor cycles on and off. We sometimes use high/low (non-auto) to keep air circulating even when the thermostat is not calling for the compressor.

Thanks Rob!
Figures, I should'a just run it in both modes and checked what happened. However, I'm always leery of the secret DW eject annoying husband button. Can't be too careful.
