That is an accurate description.
I consider changing setpoints at the thermostat to be normal operation. The ability to change them remotely or via an automation are additional options which you can choose to use or not. Of course, if you choose to use a virtual thermostat for some portion of the house, then there would be no physical device at which to change that setpoint. But, the portion of the house controlled via the Honeywell T6 would respond to changed made through the physical device.
I don't know what you were doing with your family, but I strongly suspect it was much more important than reading my document. We can't lose sight of what is really important.
There are a variety of way to connect things, depending on the characteristics of your duct system and how much control you are comfortable giving to the Hubitat App. The fact that there are many options is much of the reason that my document got so long. One option is to set them up with a "wired or" such that the equipment goes on when either the thermostat commands it or the App commands it. That way, the system continues to function normally if you lose ZWave communication, Hubitat gets stuck in an update, etc.
