To me, they're clearly describing a network boot setup.

Both "to me" and "clearly" will get you into serious trouble when dealing with legal matters. The likely outcome is that, if Apple decided to file a civil suit, or a prosecutor found grounds for criminal copyright infringement prosecution, the prosecuting attorneys would use whatever interpretation is in their favor.

I don't see how "used by multiple computers at the same time" makes any sense in your interpretation but I was trying to be diplomatic.

"Used" is a word with a very broad definition. It doesn't just mean "run as primary operating system," it could also mean "capable of reading any of the bits of," or "looked at metadata of." The interpretation of "at the same time" is also rather flexible.

I'm not saying Apple will hunt you down and sue you (to paraphrase Jon Stewart). I'm saying, unless you're a lawyer, and you have another lawyer representing you, it's best for us non-lawyers not to think we understand legalese.

I guess what you're saying is that nobody should use MacOS/iOS under any circumstances except after seeking the advice of an attorney.
