I don't know if that's the case, Caeruleus, but it could be. As you probably know, the most basic word order in a Latin sentence is Subject-Object-Verb, but if the subject is unnecessary and dropped, then you're just going to have Object-Verb and your object will start the sentence. I do see what you mean though, there seems to be a theme of pointing back to a sentence before: a pattern that Latin authors often employ (quite annoyingly) perhaps in order to make us remember what they were talking about a few lines up. On the other hand, these are fairly simple sentences so you can expect a lot of repetition as the course is drilling you with conjugations/declensions.
