Girl 1 is focused on the screen. Girl 2 senses that the person is getting too close to her behind her back. She asks if she is feeling comfortable in a stealthy way and takes a few steps back to check if that guy's groin is touching her back and he's secretly humping or is doing anything inappropriate. She gives a thumbs up to confirm with the girl that it's all okay. She comes back and continues with her work.
What's complicated about this?

I just exaggerated the humping part but you get the idea. You'd not know bad touch when you're busy looking at the screen.
That's why she asks her friend to confirm and gives a thumbs up signal.
