No... that's not what I said.
If you put a GFI breaker in the panel, the wires coming out of it will be GFI protected. You can run those wires anywhere, even to multiple places.
So, you could come out of the GFI breaker and connect to two outlets. One for the dryer upstairs and one for a new outlet in the garage. Both would be GFI protected. (edit: note that your dryer and brewery together will probably draw more than 30A, so your breaker would trip if both things were running at the same time.)
Extreme example of GFI protecting everything downstream:
At my place, my MAIN panel is outside the house. It has a 50A breaker for the central air unit and another 50A breaker the stove, and then it has a 100A breaker in it that feeds a sub-panel in the garage. Every other circuit in my house is driven from the subpanel, sharing the 100A that the main allows to flow to the subpanel.
I could take out the 100A breaker in the main panel and put in a 100A GFI breaker. That would mean that the wires going to the subpanel (and then on to everything else in my house except that central air and stove) would be GFI protected.
