I'll use right/left, which is actually how I think about it when I'm not trying to sound like a smart guy who knows bike words. When you push the front shifter all the way to the hardest gear up front, it's pushing the derailer to the right as you're looking down at it. In that hard/hard gear front/back the chain is furthest over to the right, too. I think your front derailer isn't moving any further right to clear the chain, it's hitting a limit. That limit can be adjusted out so the derailer moves right a smidge more. Does that make sense?
