You've got the general idea. Board can answer any next-to-ness question for a given Point. Consider this alternative to your fragment:
Does that mean that the Board should be able to dip into the Point's inner workings and get its X and Y coordinates? The word "Point" carries some baggage (but then so do some alternatives, like "Square"). Let's reframe the question by using "Cell". Why should a Cell know its X and Y coordinates? Clearly, somebody needs to know them, but why Cell and not Board? (You might have good reasons to go one way and not the other, but this is a good question to ask yourself before deciding.)
