It's a time paradox that follows the dynamic timeline construct. It states that, for the dynamic timeline, no matter what happens in the past, the present will not change. In this case, Mordecai and Rigby become rockstars because their future selves came to the past. Then, in the future, Mordecai and Rigby go back in time to help their past selves become rockstars because that's what their future selves did. This follows up to an infinite loop that will just repeat itself over and over again, resulting in a paradox.

The paradox is broken when Mordecai and Rigby decide to change their faite. By doing so, they have created an alternate timeline. How this loop started in the first place is inexplainable. It was just meant to happen.

It's like the episode Bad Kiss. All the things that happened to Mordecai, Ribgy, Margaret and Eileen was because Mordecai and Rigby went back in time to make those things happen. Once Mordecai got involved with his past self, he altered the dynamic timeline to an alternate one.

Regular Show doesn't stick to one type of time travel. It's complicated but fun.
