Don't worry though you'll see it soon taken as ultimate proof just like that US ads
@Ryu: even if we do have to pile up evidences pro-Aerith and pro-Tifa, the pro-Tifa evidences pile up much, much higher. And ultimately, even if kept wavering between the two, that was only during Disc One - thanks to the player - which means, with the ZaCloud personality. On one hand, they say Cloud is wavering between the two girls, but on the other hand, they also say that Cloud is wiser to none; I think in itself that it shows pretty much that this is the player who's at work there. He can chose either girl or none - or both.
If anything, Cloud - the true one that emerges later in the story - has been showed being all about Tifa. In the end, what counts? It's not saying that Aerith isn't important - she is damn important and damn dear to all of them. Aerith symbolizes his failures, Tifa symbolizes his accomplishments. And if he fails Tifa, he will also be riled by guilt and sense of worthlessness - but Tifa can ultimately pull him out of his mood when he truly needs it.
Looking back at it and putting Aerith's POV in perspective in CoLW, if she talks like this in the past and seeing how she 'tags' him, it makes me feel that her feelings are far more dilute than what they used to be in the game; he STILL is very dear and important to her, just like she is dear and important to him - but I feel that, if you think that there might have been something going on during FFVII, then it totally changed into something else. Aerith gives him those motherly feelings [I always felt that the "Mother" in AC/C was kind of the ice of the cake], but she herself looks out for him worriedly.
Maybe there's still love from her - but it's not like it used to be, it's like a very fond love for someone who messes up often and who worries us.
Bah, I babblered too much once again
