Pretty much, that's honestly my main fear. To put it into perspective, Last-Update-Suguha saw Kirito going berserk and fucking Asuna right in front of her, masturbated to it and then probably rode his dick right afterward. Then, the very next day, she knew Kirito was going to log into FOG to spend time with Asuna and she did it AGAIN. And after that she had an almost yandere reaction to Asuna 'neglecting' him.
Meanwhile, this Update's Suguha got sad and didn't even insist once when he told her he was fine after seeing Asuna's mother basically berate him and put absurd limitations in their relationship right in front of her, and then later it apparently only took him turning her down once to call Hebishima to fuck (Still not 100% confirmed but is what the narrative seemed to imply). Is like her character completely did a full-on regression/change in less than 24 hours.
