If Yuzu were to make advances on Harumin at this point in the story, I do not think Harumin would object, and this is not the first time that we have seen this intimacy between them. I bet Mei would be none too happy if she saw this, rightfully so. In the story, it also seems that Yuzu spends the overwhelming majority of her time either playing Yuri-Incest eroge or hanging out with Harumin. Very little time is spent with Mei, and when they are together it usually just involves Yuzu misunderstanding Mei or it has Yuzu pouncing all over Mei.
However, I do not think the pages and specials such as this will have much impact on the overall story. I believe that this is just to give Harumin x Yuzu shippers, along with many others, something to satiate their fantasies (Just like it does for the stalker girl). In short, it is just to have two girls being close with sexual overtones for the purpose of titillation only.
Why Matsuri runs away? Well, maybe just so that she isn't seen with the stalker girl. However, if she is claiming Harumin as her girlfriend, then Matsuri may have run away not wanting to see anymore of the conscious or unconscious flirting between Yuzu and Harumin.
