Total up all of your widths and margins of you left and right columns, and you will see that they equal more than the width of your wrapper id.
The right columns falls below the left if you narrow the browser window as it is. Once you add more margin space, it's probably lowering the threshold at which point it wraps, which led you to notice it.
