Part of how it works, I believe, is to mine info from people's contacts on other sites and services as well as LI, and play the Kevin Bacon game. I have noticed this phenomenon as well. Sometimes I am able to reverse engineer the connection, sometimes not.
As to why: their business model depends on adding members/subscribers. So they try to induce people to sign up, sometimes with spam messages that are misleadingly phrased to suggest that a friend or acquaintance is attempting to get in touch with you.
