Are you talking about not spitting mouthwash or toothpaste? Either way, you absolutely are supposed to spit. Every toothpaste I’ve ever used has directions not to swallow it.
I feel like they might be confusing their terminology up a bit. Yes to spitting, but you aren’t then supposed to swill your mouth out with water (or mouthwash) afterwards.

Oh, gotcha! Someone else mentioned a similar thing in another comment lower down too, so that makes sense.
