Nah, having used HeyGen a bit, it's extremely clearly a HeyGen generation. There's a small number of movements and expressions that it continually uses (in forward and reverse).
Edit: I mean, to be clear, it is a real person, just like the author's video is. The way HeyGen works is you record a short clip of you saying some stuff and then you can generate long videos like these of you saying whatever you want. So the stuff you noticed does come from a real video of her, but it's not a real video that's lightly edited by AI, more like the AI has a bunch of clips it can continually mesh together while fixing up the mouth to continually generate video.
If its a bunch of clips meshed together, the AI isn't doing a good job of meshing in the silence pose. I looked at HeyGen site, these are probably called interactive avatars. A woman's throat is moving (as well as her hands) as if she is talking, but her lips as shut. Whatever they are doing, they are not handling silence/listening very well.
