Eerie
Fire and Blood
I think what they mean is that CC shows Zerith more in depth, and by comparing with FF7, we see why Aerith acts like this towards Cloud - i.e., we see why she's hooked immediately, and that through Cloud, she's seeing Zack.
Of course, we already had statements from the creators, but for them to emphasize this in another game proves how important it was for Aerith during FF7.
In short, they sort of downgraded the Clerith importance in FF7 - I think that's what they mean by retcon. If you were to play the games, read the novellas and see the movie in the right chronological order, then what can be meant of Aerith ---> Cloud and Aerith ---> Zack?
Aerith fell in love with Zack during CC and never forgot him. And while Cloud also became very dear to her, it appears that, at the end of the movie, she's back with the one who never leaves her side - aka Zack. And more than them leaving together, the last images pretty much further this deep impression - Aerith had her conclusion and found her first and maybe only true [since she never knew the real Cloud, some can argue for this, especially since she saw Zack in him] love.
