Mike's test is true if the parent node is an lg and it is the first element amongst its siblings. My test is true if it isn't the case that the parent is an lg and has preceding sibling elements. In particular if the parent isn't lg then my test will be true but Mike's will be false. But it may be that in the context you know its an lg anyway...
