> If someone complied with what was asked, they would not be guilty of lying, even if a reasonable person would judge that the action did not meet the intent of the ask.

This doesn't pass the sniff test. Consider the following:

Cops: "where were you on the night of the murder?"

Suspect: "at work"

Cops: "You're lying, we found surveillance footage of you near your girlfriend's apartment"

Suspect: "ah-ha, what I actually meant by 'at work', was that I was mentally at work!"

Of course, there's some grey area where the suspect gives cagey or vague answers, but in this case by giving a duress pin, it's pretty obvious the intention was to deceive the CBP officer.
