As much as I agree with lucamarte, I think stories like this are inevitable for homura, since that's the character that was assigned to her.
I do think that these kinds of stories compliment her actions during rebellion, since if we don't assume that she's been through dozens of timelines, her line of thinking during rebellion would make her truly crazy since she rejected the happy ending that she's been waiting for. If she did went through these kinds of stories and others like it, then it would make sense that she would do what she did in rebellion when she heard of the incubator's plans in attempting to control the law of cycles, and ergo, madoka. When ever I watch that scene when kyuubey explains their plans, I think of how homura get's flashbacks of these kinds of timelines and she's like, "oh hell no" and then proceeds to take control of everything herself to secure madoka's safety.
But anyway, that's just what I think. Seriously though, why can't madohomu get lovey dovey stories like kyosaya? :<
