I don't think Google did anything intentional, but it probably doesn't matter.

They probably were doing something that would raise a flag at Google, but the Googlers knew how to get around that. So they let the app run, then let the system kill it. Meanwhile, they could do something very similar that would not raise the flag, and it'd work.

It's not intentional, but if you work down the hall from the guys who control a ton of web traffic and others who are responsible for app security, it helps. One might even say that it becomes an unfair competitive advantage.
