Due to the downward motion of her diagonal slash, it was easy for her to angle her sword vertically with the tip pointing down to block the slash, however the momentum would bend her hold on it so the tip would point more at herself. She quickly stepped back two steps, for continuing to try to fight in that situation would've resulted in quite some danger, she felt. So she essentially reset, raising her sword up in front of her in the same position she had started in, once again circling Markus whilst strafing rightwards slowly.
