in the movie there's the part were Bell is promoted for something that has slipped out of mind, but there is a view were we can see Celestine in a crowd of other gods and goddesses with other signs, and even in the manga, when Rind is dreaming, there is another goddess with a different sign.... so my idea would be that each sign symbolizes a different type of power domain (like Belldandy is more air, and Urd is fire...) and because several gods and goddesses may happen to have the wame domain... there are probably different levels of power too... like in the beginning of the manga (4th and 5th volumes i think..) Belldandy breaks her seelings to become more powerful... and at the same time, her sign changes... actually it's a pretty good question you asked...
