Okay but, at the end of the day, the opponent here was Neinhart. All of these little Historia battles probably aren't going to amount to anything (and I'm assuming Jellal / Kagura are going to beat down Neinhart and dispel the illusion before any of the sub-battles end in victory). I would consider all these Historia illusions an extension of Neinhart, not their own battles.
Erza overcame aspects of Neinhart's magic, sure, but she didn't even get a chance to touch Neinhart. So, while Erza had a 'win', she didn't really win at all. Really, she lost.
