If you pay a logo designer, you will not have that assurance either.

It is literally impossible to vet an idea / logo / website name, before you even have it.

First you design, then you apply for protection.

He's not talking about trademark protection, but copyright permissions to the assets used in the logos. I'd absolutely expect to have explicit licensing to redistribute and modify a logo, and from the T&C, it doesn't look like you even get that.
