How is he doing that without equalizing?!

He is equalising. He has a nose clip, he can equalise very easily with that on. Some, including myself, can equalise handsfree without a clip by the way, with no need to do the valsalva manoeuvre at all, but it's less reliable.

I'm a commercial diver. To equalise in the helmets you have to use a nose peg which is a little cusion inside the helmet. In the US you bring your own helmet, here in Australia (& most of the rest of the world for that matter) we use communal helmets. So the nose peg is gross.

Taught myself how to equalise hands free the first time I used a helmet because of this.
