That is exactly how it works under the DMCA, yes. There are wait times involved, so it can take a few weeks to get it back up. I am not sure if Youtube follows the DMCA or they're doing their own thing -- the DMCA doesn't necessarily say they have to put it back up or can't take it down under other circumstances, can't do their own thing. Github follows the DMCA.
