I feel like if you go into our future, then back in time, you enter into a different version of the current.

Like imagine a tree. we are at base of trunk right now. We live our lives and go up the trunk and into a branch. If we then time travel into history, we don't turn around and travel back into the same trunk.

What happens when time is reversed is that the tree is also reversed, so you turn around while on the branch, and the tree itself turns around as well, and you are still going along branch paths even tho its supposed to be the past
