bonus part in KH1?

[keyblader00]

i've noticed in the beginning of KH2 when roxas is regaining Soras memories that in Hollow Bastion in the area where you fought maleficent Sora supposedley met an organization member and actually fought him. Can someone tell me if this is a mistake or if i missed that part of the game

yeah in KH:FM you can fight Xemnas in Hollow Bastion.
he seems a LOT tougher than he is in KHII.
