It's not reverse logic even in the case of a desktop PC. Although mostly applicable to mobile devices such as tablets and laptops, there could be scenarios where you might connect your desktop PC to a public network such as an open network nearby whose signal is strong enough to reach your home, your neighbor's wireless network, or if you're offering free Wi-Fi to customers at your place of business (say, a coffee shop) and you have a PC there that connects to the same network. There could be more apt scenarios.
Furthermore, in the context of 'Network Settings,' 'Public' and 'Private' are classification descriptors for the network in question rather than that for the state of the system that connects to the network. That should help avoid the confusion.
In addition, the description in the tutorial below may help some more.
