Why breakpoint at 480 and not 620?

The modular template currently has a max-width: 480px media query that triggers the mobile (one column) layout. However, the large (multi column) layout is based on a 600 pixel wide table. In practice, this means that any screen between 480 and 620 (600 plus scrollbar) pixels wide has horizontal scrolling. I could easily fix this by settings the media query to max-width: 620px, but I was wondering if there is a specific reason it currently works the way it does.
