"Rotating pairs" means that you frequently change one half of the pair on a story or epic, to ensure constant diffusion of context about a codebase.
So for example:
Day 1: A & B work on a story.
Day 2: A rotates off. B & C work on the story and complete it. They pick up another story from the same track.
Day 3: B rotates off. C & A work on the new story.
At each point, you preserve and then share context.
