I mean, while that's ONE way of doing it, it's pretty doubtful that Fujino would change her character so much, it would be like the 3rd complete change of her character in the game made exclusively for Kirito's sake and that really feels like something he wouldn't bother with at all XP Plus, there is once again the narration's context, which I can tell now that I went and checked it myself: Kirito "conveniently" twists his ankle and suffers a slowness debuff JUST as he would have seen them going down to the undercity so that only the player sees it, which is basically another ultra-cliche NTR game situation of "The MC misses he's being NTR-ed by an inch once again". Also, after the previous update, if she was feeling horny in the first place she probably could have just followed Kirito home without him realizing and used his sleeping body again for the third time, there was absolutely no reason for her to log into FOG hoping to spend time with him but then immediately calling Hebishima when that failed. I also DON'T wanna think her new approach was completely dropped in favor of full-on character regression, but honestly this update is just filled with very blatant narration and context hints that it did
Fujino has so far done his best to keep the "plots" of the game completely separated, so it's very unlikely even if Suguha's plot isn't dropped that she would become aware of Liz's plans or vice versa, hell, she barely knows Inoda exists period, it's a lot more likely that Liz falls to Inoda without even becoming aware that Kirito's little sister was doing those things behind his back XP
