No, I have a PhD in physics and you are completely right. I had the same issue with her leap. She implies the co-moving frame is a privileged frame in SR, which is basically equivalent to saying: "SR is wrong and thus FTL travel is possible without time travel". Needless to say this is an extraordinary claim that she glosses over in two sentences of a short Youtube video.
She's obviously a very smart and professional physicist, but this video that she published is bordering on crank territory and it makes me wonder if the social media fame has gotten to her somehow. It's truly baffling.
Maybe she'll post some kind of clarification video. I'm willing to give her the benefit of the doubt that she has an interesting idea that is not well communicated, rather than a bad idea. But until then I basically have no idea how she was trying to suggest that its possible that FTL could exist. I don't really get her logic.
