No. Just to elucidate the general principle a bit: sometimes a reminder or different perspective of past learning using vocabulary you already know can be valuable. Humans aren't perfect decoding and recall machines. And that's assuming the author and target audience learned the advanced vocabulary in the exact same way, which is unlikely. Sometimes you need to fill in gaps in some of your audience's knowledge, perhaps that they should have learned but didn't, maybe because they or their teacher was having a rough day in class.
