To avoid this you would usually have to enlarge another hole, which I try to avoid if I can to not compromise the string that's already in there. And then a lot of the time that hole has a sharp bend on the grommet and is not contoured, so the string is now going around a harsh corner. To me those 2 things aren't worth it. Of course if you plan ahead you can avoid it sometimes.
That's why I love Head rackets – they actually design the racket and graphics with the stringing in mind.
