I can't tell if you're trolling or not. What's so confusing about rational actors reacting rationally to a change in incentives? Do you think there's only one way for a policy to "fail miserably" or something? Once someone knows that they'll likely have to fire some number of their team whether they want to or not, of course they'll hire sacrificial lambs. It's not like the upper management that has that stupid of a policy is going to give two shits if some middle manager claims they missed their own performance expectations because of instability in their team.
And think about the corollary: how much additional effort would have to go into monitoring managers to make sure they weren't circumventing the "spirit" of the given bullshit metric? A company like that would resemble a dystopian regime.
