I'm sure with material burst yes but in a one on one fight with normal cads and no restraints is how i'm reading this.

And did Erika just join the Onii-sama club?

It's just his low self-esteem kicks in. Though he probably consider that things like mist dispersion or material burst must not be used in the fight and thus why he made that assumption.

So yes.. the 'restraint' that he talked about might be about CAD and not about his true power.
