Not everyone understands what is being said, and instead of asking for clarity, they assume they can figure it out themselves. This is the beginning of failure, I have done this before and it did not end well.
Being ambitious is a style for some people. While some folks try hard and study deep to speak ambiguous, it comes naturally to others. Some folks speak with so much ambiguity even when it is not necessary. But the most important thing about communication is that the receiver understands you. So, try to be clear in communicating, so that you will be understood.
