Previous storytelling methods on the series have included flashbacks and flash-forwards. Speaking to Entertainment Weekly, Damon Lindelof and Carlton Cuse said that the current season "is about parallel timelines".
The duo explained that when planning for season six, they were unsure over whether to play out a tweaked timeline off the island, or one in which the attempt to re-write history did not work.
"We thought just doing one would not inherently be satisfying," Cuse revealed. "We've designed each season to be its own thing. This season is about parallel timelines.
"The thing that was appealing to us as storytellers is that in hitting that reset button, we get to make the show really feel like season one. We're basically getting to tell origins for that characters all over again."
Lost continues Tuesdays at 9pm on ABC in the US and Fridays at 9pm on Sky1 in the UK.
