Sample size is one, and they might've discussed this before. Someone with good written communication skills can write effectively, without too much details, quickly on the fly. The same holds true for verbal.
I believe there's two important key points: confidence (but not overconfidence) and empathy/sympathy. Putting yourself in the other person's shoe and figuring what they need to hear ie. not what you want to express. The latter is secondary!
Sure, you can practice it, but only so much. I have autism, and I'm utter shit at this (even in my native language). I've been practicing it pretty much all my life (I remember having issues with it at elementary school). I'm terrible with being to the point and keeping communication short. And if it is short, its usually too rude.
