No, he fulfilled the minimum requirements for the bonus before he left the company, however the company did not specify at what point the bonus was due to him. For example, my company rewards annual bonuses based on the calendar year, however they do not pay out the bonuses until April. If you leave the company between Jan 1, and April, you do not receive the bonus. While it might not be the most moral practice, it is a well established practice.

Of course it did.
Quote from the article:
the payout was contingent on said employee staying for a minimum of a 6 month period at the position
If that's the really the full text of the agreement (which seems plausible to me, I've seen similar e-mails) then there is nothing unclear about that. Even if he had quit immediately after referring that other guy he'd still get the bonus. Period.
