Who knows how far into the future she is from? If 3,000+ years, it could be very easy that the decade-specific details so obvious to us are mere blurs to folk studying the past from her time period. In this respect, she may have not been aware of all the time-period relevant clothes and accessories she was supposed to bring with her on her trip; her and her friends probably brought their phones with, she whipped hers out, dialed the number, didn't hear anyone on the other end, started walking about shouting at them 'CAN YOU HEAR ME NOW!?', and then looked toward the camera to figure out what the hell that strange-ass archaic-looking crank-box thingy was with which some guy was busy playing. It would certainly explain why the man walking in front of her was walking away from her so quickly!
The problem is that we can come up with millions of such ways to explain this as a time traveler from the future and an equal number of ways to explain it as something else, none of them possessing the slightest shred of evidence. So while it makes for endless speculation, it is not something we can answer definitively, and so instead of drawing ANY conclusions on this woman and what she is up to, the furthest we can go is to say this: she is walking; she stops walking; her hand is by her head; she is talking; she looks at the camera.
Anything more than that is just imaginative speculation.
