When I see an image with a turtle and a dog in it I tag it turtle and dog, even if the turtle is just a tatoo on the dog's ass.
Yuri and futa in one post just don't seem to be... contradictory in any way to me.

It seems pretty damn sexual to me.
Ditto. Remember, when in doubt, use the Pulp Fiction test.
Much as I consider myself a yuri purist, for the purposes of tagging that image needs to go under yuri. We can't ignore what Remilia and Sakuya are doing, even if the foreground "ruins" the picture for me and some others. At least that's my feeling right now. I don't remember what I concluded on this matter previously but don't plan on rereading it and second-guessing myself.
So yes, there will be rare multi-couple cases where futa might appear in a yuri image. If this were a very common thing then perhaps we'd need to come up with a more nuanced solution, but the multi-couple condition in post #851759 isn't terribly common.
The solution here is to blacklist yuri futanari on one line, I suppose.
