If she become proficient enough it won't matter whether a guitar is right handed or left handed, she might be able to play both.

My last guitar teacher was a lefty but was so used to the majority of guitars being right handed that he could take a right handed guitar, flip it over to play left handed (ie. guitar upside down), and was just as good that way as he was when using a left handed guitar.

And all of this reminds me of something I once read that said that we should all be picking/strumming with our left hands, regardless of which is our dominant hand, because the right hemisphere of the brain controls the left side of the body and that right hemisphere is the creative side that is responsible for rhythm, etc.

The left hemisphere, which controls the right side of the body, is responsible for words, logic, sequences, etc. which would make the right hand better for fretting.
