> The FSF is not a court of law. As such, their opinion on the interpretation of the license has no particular standing. It's helpful that they're the author of the license, and if it came down to it in court, it may be persuasive. But another lawyer might have a different opinion...

A key word there: "another lawyer".

So sure, if there was another lawyer here who in their professional opinion will state a contradiction, then that is indeed something worth to consider. An non-lawyer however, has about the same qualification in defining ambiguousness in legal documents as a non-engineer has in defining faults in a nuclear reactor.
