If she assumes him possibly indicating intent to not stop to be actually taking pictures, then maybe you're right, she didn't lie... because as Chomsky pointed out in a talk I saw recently, the accusation of lying implies the capacity to tell the truth, which requires a level of mental processing out of the reach of the FA... so as you can see, at least for me saying she lied is the kindest one of all available options.
