If someone came up to you with a puzzle involving transcriptions where there is an expectation that some of the inscriptions are true and some of the inscriptions are false, and nothing the person actually utters is false, then that person was not lying.

In contrast, if someone came up to me and gave me something that looks like a legal notice -- a scenario where there is NOT an expectation that the notice might be false -- and it turns out that the notice makes false claim, then that person is indeed "lying", especially if, when I take the notice and say "Thank you" and start to close my door, the guy says "Actually, you have to pay the fine immediately; you can't just mail it to the police station later" or whatever.
