Its because they are desperate for a moment they didn't had a positive moment since P1 so they will take anything they can and twist it so it can suits their needs to convince themselves that SS is gonna be canon despite being DEAD for a very very long time , they have what i call self insert delusion .
As for 540 i've said this a couple of times what the nin said " if its somebody that you like , then they are bound to be a great person" which means not everybody that Sakura likes/liked are a "great" person and she's sad by the fact that she ever had feelings for guy a like him this imo in no way did it confirmed Sasuke as the only guy she loves/loved or that she prefers Sasuke over Naruto it only confirmed that once upon a time she had feelings for him which we already knew that .
Also again " if its somebody that you like , then they are bound to be a great person " this also established that Sasuke is not the one she really likes/loves but the great person that is in her life and we all know who that is NARUTO . 540 is also what is know as Red hearing - its a clue that is meant/intended to be misleading or distracting .
I ran out of likes again! D:
Anyway I liked this...I liked this a lot.
I have tried to explain the whole idea behind a red herring, seeing that the this seems to only hint that she is just now realizing, or maybe she realized it earlier, either way, we see her looking said when thinking of Sasuke.
To me, I have no idea how that scene can be taken as good thing for SS, it has, and always will, look anti-sasusaku to me.
