In all due respect, if it did, I would not of posted this thread…

Many times, such info can be ambiguous and very confusing…

So no, it does not answer my question…

So I ask again, can someone shed a little light on what is going on here???

Well this is used for relationship definition. Its safe to remove it, but it tells search engines that you have interrelated data in-case your site has something like that. As defined on the gmpg site too, with examples that you could link your friends / relation on the site and allows search engines to gather relation data.
