N5 Sentence Order Question (What’s More Natural?)

In my textbook the answer to some questions are as follows:
あそこにバス停があります。

山下先生はあそこにいます。

why are they in different orders? does it matter? i mean i know both ways [thing][direction][あります・います」are both correct, but which way is more natural and why?

cause in each of those sentences, it's flip flopped. is it arbitrary or is there a reason?
