In between the Main Phase and Attack Phase is the "Move Phase".

At this point, you can use Move as many times using Monsters with the Move Keyword to an Open Space on the field, emphasis on Open, but you can only Move a Monster once and one at a time. You cannot swap the current positions of the two Monsters using Move alone.

In your example, yes, if you wanted to Move the Left Monster to the Right Space, you would have to Move the Right Monster to the Center, then Move the Left Monster to the Right Space.
