That was actually my first thought too.
I then went and watched a video with the parallel guide extensions to see that it acts as a "fence" Or stop to the right of the blade similar to this.
I'd think as long as you aren't providing pressure from the right like the clamping elements as an example, chance of kickback is probably diminished.
Course I could be wrong here. I'd love to see a video and better understand whether or not kickback is a concern.

First thought in my mind is "kickback". Is this an issue/does it concern anyone else?
