Yes the issue is that he pushed it downwards a bit, and also the ball gives some of its energy to the hammer. This means that the hammer is travelling faster and thus goes higher than he expected.

From the spin on the hammer after it hits his face it looks like there was a lot more energy left, but I'm no physicist so I have no idea where it's from.

Yes, I'm unsure whether he's just guiding both bodies of if he actually pushes them, but if, it's just slightly. The vast majority of the additional momentum of the hammer comes from the ball. You can see just how low the ball bounces back. Not even half of its initial height. The 'missing' momentum (or energy) is mostly transfered to the hammer, the rest is dissipation.
