I think the problem is, the way he talked about Rin and Saber, what I was expecting was the reunion with the people he actually loved; because all along, whenever the Sekirei came up, he talked about their feelings, or how he dealt with them; but if it was those two, he talked about his feelings, how he felt about them.
What Gabe has done, is hold the "Sekirei Magic Wing Bond" in one hand and "Shirou doesn't do things for himself" in the other, and smacked 'em together; but the result wasn't new and interesting, it was just... sad. And not sad like melancholy or cathartic, but rather, they smooshed together and cracked like dry playdough, and it was pathetic.
This chapter reminds me of Heaven Feel True.
It's not as well written, but that feeling that everyone around Shirou is congratulating him on living for his own sake, when the way they did it was push him into throwing away the dream and ambition that he held, that he relied on as support when he was in bad places in his life. It's like, "how can he really be fixing his lack of ego, if what happened is he let people talk him into abandoning the one thing he cared about most?"
This is a story about Shirou betraying himself. And nobody around him even realizes it.
