A left handed bow means that she is left eye dominant.(I am right handed but left eye dominant) You need to know this kind of thing when you do archery and long rifle/barrel shooting (guns). (most people don't know that kind of thing. Im not saying you don't, but its for others just in case)
I was not so much thinking about it being a left handed bow but more as to the right hand position on the bow being a little low compared to the angle the arrow will travel, but in saying that when fully drawn it may look different
