Wow, that's a really shit way to do it. Bare minimum, it's going to take a couple of seconds to re-negotiate the link. Depending on the connected devices and how they're configured, it also might sit there and try to re-acquire an IP address rather than just assuming it should continue using the one it had (some devices do this when they lose the ethernet link for long enough). You could end up breaking connectivity long enough to dump yourself from the game.

Well remember they only hook it up to the upstream. So they still maintain a valid link (at least for long enough to stay connected). There is a little bit of time to reconnect the upstream, but not like if they switched off the entire ethernet cable.
