Yes except,
the liquid is sent through the smaller pipe because ........can you
imaging all the noise that much liquid would make sending it through a
larger pipe? Thats why the small line is insulated. To keep down all
the rushing liquid noise. Sometimes, if it gets to noisy you can put a
flow control valve in the line and throttle it down to dampen the
liquid rush noise.

If they didn't do this everybody inside the house would piss themselves with
all that gas passing noise.

With furnaces, we use the term "supply" and "return". So, the one pipe
supplies the evaporator (outflow, our out from the unit) and the other one
returns the refrigerant to the compressor. So, I think they are labelled
backwards.

The big pipe is marked outflow: from the house to the unit.

The little pipe is marked inflow: from the unit to the house.

And so the heated gas is sent to the outside unit using the big pipe
(3/4" diameter copper). The outside unit removes the heat. And then
what is sent into the house should be a liquid, which is why the pipe
is smaller.

Is that correct?

The only things that's backwards is your logic.
