There seems to be this perception out there that Clash of the Red Rangers making the events of RPM take place in an alternate dimension was some huge, earth-shaking change, but it wasn't, because those individuals who were involved with RPM - particularly the original showrunner, Eddie Guzelian, and long-time PR writer John Tellegen - made statements during the season's initial run indicating that it was meant to exist in its own, self-contained reality, so the only thing that Clash of the Red Rangers did was to explicitely confirm 'in-universe' what had already been in the minds of the PTB behind RPM.
