Honestly, the host was awful (constant stammering) and that combined with Alexis's naivety (with regards to how to present points) made the opposition argument completely worthless. If I had no knowledge of why SOPA is bad I would have come away from that video with the opinion that SOPA is fine...
I'm not sure why in any broadcast I've seen someone doesn't give examples, why doesn't someone opposing SOPA say that "If a person goes to Facebook and posts a link to thepiratebay.org then Warner Brothers can request Facebook be taken offline"? Surely that is more than enough to explain the problem.
From that though it sounds like it is possible, given a judge willing to take some liberties with interpretation of SOPA. Unless it's explicitly not possible it's still fair game to suggest that the bill is opening up that possibility.
Given that content producers do things like claim every pirated copy as lost income even though in reality they know this isn't the case I think taking the powers given by SOPA to the extreme case could be a good tool in the argument.
Wait, #2 and #4 would also have to be true for this to be possible. To answer your question, it's explicitly not possible, because Facebook.com is domestic and is not primarily designed or operated to enable or facilitate infringement.
