Curious detail I was wondering about

I've gone back and watched some of the show and I noticed that Ezra uses both hands when using the force to push enemies while Shin only uses one hand to perform force pushes and such. I'm not sure what this means it could just be two different types of ways they've respectively trained with the force. I like the way they differentiate between Ezra, who is grounded and balanced, and Shin, who is swift and rapid. Any ideas?
