Generally the sources did not really concern themselves with left handers. People were just expected/"encouraged" to learn to use their right. Even my mother was still forced to learn to write with her right hand. On top of that, the Messer plays in the Glasgow manuscript do not even cover attacks from the left side, but you can extrapolate. That being said, where you have to step, to the inside or the outside, is depending on which foot you lead with, not the hand. That is ultimately the difference between play 1 and 2. Glasgow wants you to do a triangular step, a passing step to the side and forward, and not cross your feet. So, in that line of thinking, if you were to engage another fencer with your left hand and left leg forward, you would still step to the inside of your right handed opponent as in play 1, and if you were to lead with your right foot, you would step to the inside as in play 2. - Peter
