Yeah, the idea was that it would have some sort of protection properties when water or dew was sprinkled from it. Either that, ir flinging it as if you were sprinkling something produced blood that would still have protection properties. But, I don't know enough about Passover besides the basic "They put blood over their doors so they would be spared from a mass death".
