Once you reach the point rotating the crank where the intake valve begins to lift, you would have to keep rotating the crank through 720 degrees to reach this same point again. Does that make sense? There are probably other ways to describe this, but I can't think of another quick way to answer what I think your question is.

Rotating the crank only 360 degrees would get you to the same point on the opposite cylinder bank. Each cam takes two crank revolutions to make one complete cam revolution.
