A dragon's basis is determined by looking at the dragon in the game, watching how it moves, comparing the animations and behavior, and so on. It is not accurate to only compare the still images on the wiki, because some of them were made from screenshots of moving dragons, and thus you may not see poses matching exactly.

I hope that helps clear up the confusion. :)
