I have to say that the video is quite ignorant towards the Yuri genre as a whole and perpetuates the western concept that Yuri equals porn. It really must also be keep in the forefront of the mind that just because there is sex or sexual situations in a Yuri manga or anime that does not make it pornographic or "borderline-henati" purely meant for sexual enjoyment. Of course there is pornographic Yuri out there, but over all Yuri is about the sexual, emotional, or both aspects of lesbian relationships. I'd also add social and cultural elements of being a lesbian though those two important parts are not often touched on. All Shojo-ai does is further Yuri being seen as "hyper-sexualized".
The harm both series could bring to Yuri is if the viewpoints presented in the video are perpetuated throughout the widened viewer-base outside the manga community. I haven't read NTR, but I've been keeping up with Citrus since it started releasing and it wasn't until after the anime announcement that I have seen discussion over it being potentially pornographic. It's not the best story, it's repetitive, and sometimes I think some of the erotic content is taken too far. However, some of it is also fitting within the context of the relationship and later in the series they have started to address the cultural issues that stand in the way of lesbian relationships. I do not believe there is enough for Citrus to have much impact on "normalizing" lesbians relationships, but it is a start. There are other series that would serve this purpose much, much better. That said, Citrus could have a positive impact as well if viewers pay attention to what the story is trying to tell and not the superficial elements.
However, any impact I think will have far more to do with reception from a wider audience along with preconceptions of what Yuri is as opposed to what it actually is.
I think for now it's a "wait and see" situation.
