Yeah you guys are missing this - not supposed to be a new update but a fix to the last one that everyone was complaining about.
The writing still isn't awesome, but this change makes a lot more sense for the progression of the character. There is two things:
A: No new random dude that instantly gets to 3rd base with Rachel out of the blue;
B: Rachel clearly being jealous that John is getting action from elsewhere, and acting out of spite on that basis. That is better character progression for the story.
So this is, IMO, a lot better of a version for the Ch10 update than what we had before. I think the comic format can work, but it has to be done better (IE no miniature text, better leadup to the images) and they should introduce some other creepy old man characters, just not so quickly as they did.
