Left handed means it's for someone who suffers a left handed handicap.
So they (a left handed person) would play on the neck with their right hand and strum with their left.
Imagine the guitar in your hands and which hand the neck is in and which hand you'd be strumming with.
If you're playing on the neck of the guitar with your left hand and strumming with your right hand, it's a right handed guitar.
