For example: you come to the TVCH, see 5 threads with new posts. You only read 2 of them. You turn off your computer and come back an hour later. Nobody has posted since you were last here, (pretend it's a slow day ) The arrows are all gone now, even though there are 3 threads you didn't read, the arrows are all gone because you had the chance to read them, but didn't. If someone else did happen to post into one of those 3 while you were gone, that one thread will have an arrow.
This is my understanding of it, but I might be wrong. I didn't create this feature, it's built into the software we use.
