My inexperienced ears tell me the high sound is disconnected from the low. Plus, the high sound is pretty thin. Thus, I don't see it as head voice.
Going a bit off topic: Head voice is a tricky concept. I have just covered it with my vocal teacher and, to be honest, it's not something you should force yourself to do. It is something that comes naturally as you go up the scales if:
- your throat is free (hard to achieve that)
- psychologically, you do not think about having to reach to hit the high note
It's almost counter-intuitive that, the way to hit a high(-er) note in head voice is by not thinking/concentrating on the fact that it's high, but that's how it works.
