Meta-Families don't interact with each other

Hi, in the wiki it says that all meta objects influence each other, no matter if they belong to the same family or not.
This isn’t the case here, only the meta objects of the same family interact with each other. Am I doing something wrong or is there a mistake in the wiki?

Here is the wiki entry: http://wiki.blender.org/index.php/Doc:2.4/Manual/Modeling/Metas
At the bottom, you find the sentence “meta objects always influence one another in the usual way, whether or not they are members of the same family”

Better to view 2.6 wiki, but there they don’t mention families. But they do say ‘all’ metas interact but they don’t. So either it is a bug or the wiki is wrong. Not sure which.
