I say no: it's entirely on topic.
The answer may be that "there is no correct way" or that "it's subjective as to which way is correct based on design" -- but IMHO that's an entirely valid answer.
Some things in construction are done for aesthetic reasons, others are done for safety or structural or practical reasons, and to a newbie [in that area] it's not always obvious which is which.
Let's pretend the answer to this question is "You never want more than 5 or 6 planks that are less than 3' long in a row, or they'll start buckling as humidity changes" (to be clear: this is not true). I may be wrong, but if this was true, then I think this question (maybe reworded slightly) would be considered on-topic, and this to me is the problem: whether the question is on-topic or not should not depend on what the answer is.
