I absolutely agree, it's much easier to find out whether someone understood your message, or what they actually want to achieve, or whether they know what the goal is, when you have additional cues.

Once you have less need for these cues because everyone is open and says "I don't understand what you are asking, please rephrase it in simpler terms", or "I have no idea what this project is. Do you know what our goal is?", it gets a lot easier and quicker. But it's very hard to assemble a team that does that well.
