Good question. Think of it as a "gentlepersons" agreement not to actively poach someone from another startup with common investors. Similar to how investors generally don't invest in competitors to their portfolio companies (but it does happen-- See KPCB investing in both INRIX and Waze). It was more of a guideline, rather than a hard fast rule. This agreement didn't prevent people from recruiting friends, or from people actively looking to join another company. Also, if the person is/was unhappy at one startup, the investors would prefer they join another portfolio company rather than not.
