Chronologically, Redguard was earlier than other games. (In-game Chronology, I mean).

I see your point about the High Rock invasion being the same, but I think there were still actually 3 invasions. Vivec's Sermon's do mention 3 invasions of Tamriel, although it is highly alegorical in nature, so it possible that it means something entirely different.
