I am not really understanding why the solution is the one that is shown in there.

I understand that if you make both pieces together, it forms a rectangle, but in the puzzle description, it says: "Where should you cut the paper if you want to turn the paper in Diagram 1 into a rectangle without flipping either of your two pieces?" Yet it seems like at the end, you need to rotate one of the pieces so it locks with the other one, right? 😅
