No problem doing that. But when you join the pairs, sew them from the opposite direction - it prevents the strip set from bowing.
As for your first question (if I'm understanding it correctly), when you're pressing all to the left, the centers are both at the top, right?
So when you go to sew the two sections together, the seams will actually be pressed in opposite directions, and will/should nest nicely.
If they were all going in the same direction, you'd have a lot of bulk at each seam join.
As long as your were pressing in opposite directions for the bottom and the top sections, you could do it as you joined the strips.
