Yes, and this is something you don't start to fully notice until your second playthrough. For some reason, I never gave it much thought the first time. The same conversations and banter comments repeat ad infinitum every time you pass an NPC. The worst place to witness this is in Loredo's camp during the 'Indecent Proposal' quest - those damn guards sitting around the campfire cycle the exact same conversations (two of them, I think) all the time; I'm serious, it's not even 30 seconds in between each one. It's absolutely ridiculous, and I can't believe this is intentional. Something in the script must be missing; something that adds a cooldown between conversations and other banter, or at least something that prevents the same line to be played more than once per day or something. I refuse to believe this was a conscious design choice made by CDP, and it must simply be an oversight somewhere.
I've just started my seventh playthrough, and this problem started giving me a migraine a long, long time ago. This must be addressed.
On another, semi-related note, while the banter itself is really well-written, it does get weird at times. Chorab in Lobinden is scripted to tell a story to the other villagers (I think he has two of them: Adda, and where Lobinden got its name). What's causing a problem here, however, is when this conversation triggers without the villagers first gathering around the campfire, as they are supposed to. I've often ran through Lobinden to find Chorab either sitting on a bench on his own, talking to himself, or even hearing him tell his stories from inside his house! It's really silly, in a fun way, but I assume it might be related to the original issue. I'm ready to blame the same lack of a specific script, or some other bug/glitch in the coding.
