He might be talking about "alternate parallel realities" which may be fractally structured. The conventional idea of time travel is along a linear past-present-future time sequence. Fractal time allows for more than one time dimension, side-stepping.
He also mentioned the role of consciousness. The reality fractal already exists in potential form; which branch is experienced is a matter of conscious intention.
I wonder whether the main purpose of QAnon has been to focus the intention of thousands of passionate patriots toward a desirable branch of reality. The key quality of consciousness that attracts a reality is expectation, which would be the result of total belief that what QAnon writes is real.
