Yes, I'm sure. I haven't seen any forum software, anywhere, that didn't indicate that a thread had posts made after you had last visited it. Every time you visit the forum front page, you'll see which threads have new posts, even if you've already seen them.
If, on the other hand, you're accustomed to using vBulletin's "previous thread" (which wasn't how I understood your explanation of what you used to do), you wouldn't have
seen threads which had new posts. However you could easily have totally missed some threads if they were refreshed before you reached them. If that's what you want, you can just continue, using "LIST NEARBY THREADS" to choose the thread next after the one it shows you to be on.
Here are a couple of images from yet another forum I also frequent. I haven't been there in probably a week or so before today and this post.
The first image depicts the sub-forums. The ones that are marked red are sub-forums that I've visited previously. The ones marked in blue, I've never entered before.
The second image depicts threads within the sub-forum. The ones which are bolded are completely new since my last visit or are threads that I've never visited that have new posts. The non-bolded blue ones were there during my last visit, but I never opened the thread. The ones marked in red, I've opened previously (doesn't matter if I've posted there or not, or if there have been new posts since I've been there last - it stays red as an indication that I've been there before). There are other threads on the forum which are 30+ pages long, which are still colored red (previously viewed) even though I haven't visited them in months or years.
Again, you can EASILY look at those threads and tell the differences between them. That's not the case with the current setup here. They may be different, but much harder to distinguish the differences if you aren't carefully looking. Hence my previous comment, that you should be able to tell the difference even if you were drunk
