I don't get it...

Supposing that there is a close relationship between the Princesses and the Keyblade, it seems likely that they will resonate with each other...

I have chosen one special girl. I do not know if she possesses a power like that of the Princesses. But, there is a chance, and this is an experiment. She may lead me to the place where the one holding the key is...

I shall send her off to the ocean of other worlds.

Xehanort found Kairi on Radiant Garden. Believing her to be a PoH, and wanting to find the Keyblade Wielder, he threw her off of RG in the hopes she'll end where the Keyblade was.
And she did, having ended up on the world Riku was on.

Kingdom Hearts is all about connections. Part of the charm, imo.
