Why are floating mussels to be discarded before cooking?

I'm trying to cook mussels. Looking around various sites, I am told to throw out any mussels which float in a bowl of cold water before cooking. Other sites say not to worry about it, they have eaten many floaters and been fine. I know not to eat any which will not close their shells or which are not sealed properly, but I have a batch where most of them float, but otherwise respond as "alive" closing their shells etc. I'm confused?
The Joy of cooking, my usual fallback for cooking discrepancies, does not comment on the floating / sinking issue, just that they better be closed before preparation. Does anybody know why the floating ones should be discarded? Any other mussel insights?
