The pics didn't show.

I do see your point. However, unless the show specifically states they are the same island, we can't just assume it. It is also possible they could be "recycling" images or something like that. (Its also possible I haven't seen Riders or Defenders in a long time!). However, I think it is entirely reasonable to put in the trivia of both places suggesting that they may be the same location, so the reader can form the opinion themselves.
